Digital Transformation for Energy Networks
Atsushi Hiramatsu
NTT Advanced Technology Corporation
1. Introduction
Digital transformation (DX) is the world-wide
movement these days. Various information andcommunication technologies including the Internet ofThings (IoT) and artificial intelligence (AI) are used toinnovate and enhance the conventional business andwork processes in many industries and organizations.
One of such examples is the recent dramatic changes in
the work styles and learning methods under the global
COVID-19 spreading. Multi-media communication
tools and broadband networking technologies helped
world-wide office workers and college students to
instantly work, study and collaborate from home or
remote offices. DX is not just converting analog signals
into digitized data or handling the information bycomputer software but reforming the whole processesof the industries and organizations and creating new
business models or novel work-life styles. This paper
overviews the current trends of digital transformation
in ICT, car and energy industries, and shows the ICT
technologies will play important roles in the future
fusion of many industries and societies.
2. Digital Transformation in ICT Networks
The impacts of DX can be seen in the history of ICT
networks (Fig. 1). In early days, the telephone service
relied on human switchboard operators who connectedlines for analog voice signals between speakers by theirhands. To reduce the burden of operators, step-by-step
automatic switching systems were developed, andanalog crossbar switches later improved the switchingsystem capacity (Fig. 1(a)). Then, the digitaltransmission and switching technologies wereintroduced to remove the distance limit intelecommunications and to expand the switchingcapacity by time-division technique. Also the computer
software is used to control switching systems in placeof logic circuits. This enabled network service
providers to release new services quickly and upgrade
their services easily (Fig. 1(b)).
Once the network core was digitalized, theinnovation of ICT networks was accelerated. All ofvoice, video, pictures and documents can be encodedand multiplexed as one stream of data, and thedigitalized information can be transferred not as
continuous data stream, but as chunks of data bypackets with routing headers. The software forcommunications services does not have to directly2

control the switching systems and can be executed onservers remotely located in the network (Fig. 1(c)).
Then the Internet based on packet network
technology had spread quickly and became a global
service infrastructure for various communication
services and unique applications such as World-WideWeb, Social Network Service and E-commerce. Also
the dramatic progress of the technologies for very
efficient and flexible wireless communications
provided all users with mobile broadband access to theInternet from anywhere anytime. Virtual network andvirtual machine technologies were developed to divideand share the network resources and computing powerin the “cloud”. Now novel technologies such as IoT
and AI are blooming (Fig. 1(d)).
Digitalization conceals the complicated physical or
analog behaviors at the point of physical-digitalinterface. In the digital world, it is possible to virtuallydivide, combine or share those digitalized objects andto gather huge data and extract the hidden relationshipbetween independent events. Also the knowledge fromthe different fields can be integrated. All thesefunctions and operations are software-defined. This is
the driving force of the DXs to generate new ideas andnovel business models.
Recently, “Innovative Optical and Wireless Network(IOWN)” has been proposed by NTT [1]. This aims at
transforming the current ICT network architecture by
all photonic network technologies with digital twin
computing functions for innovative data processing andcognitive foundation functions for service orchestration.
These technologies will further accelerate the DX ofother industries and societies.

3. Digital Transformation in Car Industry
DX in car industry has already started. In old days,
cars were mechanically controlled by levers, gears andoil pressure pipes. Handles, gas pedals and even speed
meters were directly connected to the target objects
through such mechanism (Fig. 2(a)). When the parts ofthe car control are realized by CPU and software in acar, the digitalization of the car industry started (Fig.
2(b)). The technologies for autonomous car drive havebeen studied and released step-by-step to the mass
production cars. Recent cars are full of sensors
connected to the CPU through a car internal data BUS.
Moreover, the electric vehicles (EV) using a motor anda battery have been commercialized and is accelerating
the digitalization of cars (Fig. 2(c)).
Now most of cars have mobile communication
capability to obtain various real time information
including road traffic, accidents, hazards, and local
information along the driving route. Using thiscommunication capability, it is considered to connect
all cars to the network AI functions or to each other.
The aim of this “connected car” is to coordinate themovements of all cars. This technology is expected tomake the autonomous car driving more comfortable
and safer. Also new applications utilizing power stored
in EV’s batteries might be proposed (Fig. 2(d)).

4. Digital Transformation in Energy Networks
DX of electric power networks is expected to start
now. There are two driving forces for this change inelectric power industry. One is the effort to tackle theglobal warming issues by increasing the share of thegreen energies. The other is the preparation for the
recent increase in power grid failures caused by natural
disasters. At the Great East Japan Earthquake in 2011,
the electric power grid were severely damaged and theatomic power plants were shutdown. In 2018, theblackout occurred in Hokkaido Island after anearthquake. In 2019, the electric power grid is heavily
damaged in Chiba prefecture by a big typhoon.
In order to promote the diversity in the electric powersources and to improve the resiliency of energy
networks, the energy network reform has started. Thistransition in the energy network can be depicted as inFig. 3.
For long period, the electric power grid was closed
one-way distribution network from conventional hydro,
fossil, and atomic power plants to home, offices andfactories (Fig. 3(a)). Then, when the global warming
was widely recognized as the real threat, the power grid
became open to new energy suppliers using wind,photovoltaic and bio-mass energy sources. It was
expected to increase the share of the green energies inJapan (Fig. 3(b)).
Now, “Energy White Paper 2020” from the Ministryof Economy, Trade and Industry [2] predicts that theenergy networks become two-way. This means thepower consumers can feed their power to the energy
networks when they generate power from their own
power equipment more than they need or hold enoughpower in their own batteries. For example, back-up
batteries in local telecom offices or EV batteries can beutilized to support local communities at disastersituations [3]. It is thought that the utilization of
distributed power is one of the effective options toenhance resilience of power systems against natural
disasters (Fig. 3(c)).
It is also expected that new business models such as
power aggregators emerge. Power aggregators manage
power from small power sources such as wind power
plants, bio-mass energy plants, home and officephotovoltaic panels, and the electricity stored in EV’s
batteries. They sell the aggregated power in the open
power market as big power plant owners. Virtual power
plant (VPP) is the technology to monitor and control
the power flow from small power sources as one plant[4].
To promote the DX for energy networks, the tightcollaborations between ICT experts and energy
network experts will be required. The technologies
studied in ICT networks are useful for managing twoway energy networks, such as bi-directional networkarchitecture, network virtualization, IoT, and AI. One
example is the concept of “Energy Internet”, which
proposes to build energy networks based on the similar
criteria of the Internet architecture [5]. However, thedeep knowledge about the analog behaviors of power
grid is no less important for stable and safe operation ofdigitalized energy networks. Thus, the collaboration of
ICT and energy network engineers are inevitable.

5. Conclusion
DXs in many industries look similar, and ICT
network technologies such as IoT, AI, mobile andvirtualization are commonly exploited. This means
technologies studied for ICT networks can be used topromote the DXs for other industries, such as energy
industry. It is expected to encourage IEICE members tocommunicate and collaborate with research societies
for other industries much more.

IEICE Communications Society – GLOBAL NEWSLETTER Vol. 44, No. 4Some Fundamental Concepts
Underlying My Research Activities
Masaki Aida
Tokyo Metropolitan University
1. Introduction
Science & technology and religion are often talked
about as being incompatible, but is that true? It was not
so long ago in the history of humankind that science
separated from religion, furthermore, it was only recent
when technology was systematized as engineering.
Both science & technology and religion are the resultof human efforts to create a “complete system,” and I
think that the structures created by humans all havesomething in common. For example, the formulation ofphysical laws based on the principle of least action thatappears in analytical mechanics seems to be motivatedby the thought that physical laws should be derived
from the first principle. This vision seems to be
conscious of something that governs the laws of theworld. In more detail, the existence of physics itself isbased on the wishful assumption that the laws of theworld are indicative of a beautiful system (which canbe understood by mathematics). We may be able tointerpret this is assuming the existence of God in asense. Interestingly, the wishful assumption of physics
remains undeniable after many measurements andvalidations and is still a force driving human effort.
In science and technology, “facts” that can beverified by experiments are sought after, and appeals to“the way it should be” are supposed to be denied. Ifthese appeals are not adequately suppressed, there is arisk of biased observation that precludes direct
observation of reality and generates incorrectconclusions. However, if there is no intimation of
direction, the individual will be unable to secure guides
to the understanding and systematization of unknown
phenomena. Therefore, some intimations about how toproceed with research are necessary, making balanceessential.
This essay introduces the fundamental concepts
underlying my research activities. These have been
introduced in detail in my Japanese textbooks [1], [2](they are also outlined in [3], [4], respectively), but I
will take the opportunity of this essay to elucidate themin English.
2. How is the Order of Our World Created?
The development of ICT has strengthened the linkage
between users and information network systems. As aresult, user behavior has come to affect the stable
operation of information network systems. For example,
the email generated to exchange New Year greetings is
so large that receiving emails becomes problematic.

Furthermore, the influence of the user's behavior also
affects the behavior of other users via the information
network. For example, when a web page takes too long
to be displayed on a personal computer due tocongestion of the server or the network, the user often
clicks repeatedly. This behavior further loads theinformation network system, which makes it difficultfor other users to display their requests, and therepeated click action propagates to other users.
Following these considerations, it is difficult to think
about the performance and stable operation of
information network systems as a single isolated system,
and it is necessary to enlarge the scope of the target toinclude users' behaviors. Furthermore, considering thatvarious sensors and self-driving cars will soon beconnected to the information network, the entire
information network system will become massive inscale and complexity. It must be emphasized that noone knows all the details of the current state
information of even the current information network
systems. How can we properly operate a system that we
do not know the whole picture? One way is to find asystem that does not know the whole picture but isdeemed to work well, and to draw conclusions about its
mechanism.
The most well-known large-scale and complex
system is our world. The number of components thatform this world and their diversity readily confirm that
it is the ultimate large-scale and complex system. So
why is this ultimate large-scale and complex system,
the world, stable? We believe that the world will still
exist tomorrow and that the sun will rise tomorrow, justas in the past. Even though we know that no past stateis ever repeated precisely at the scale of atoms orelementary particles that make up our world, we
believe that the world is stable. Such orderly behaviorof the world is created through so-called synergistic
effect, self-organization, or the collective phenomenaof fundamental structure. This framework is exciting
and gives useful clues to engineering. The question ofwhere the stability or orderly behavior of the worldcomes from probably corresponds to the following
questions. Assuming that God created the world, what
divine secrets were used at the Creation to yield theorderly behavior of the world? Conversely, even if we
assume that God does not exist, what are thecharacteristics that make us feel that something isbehind the orderly behaviors of the world?
If the characteristics indicative of the order in nature
are known, it should be possible to create a mechanism
5[From CS Fellows]

IEICE Communications Society – GLOBAL NEWSLETTER Vol. 44, No. 4

for creating order in a system by recreating it in anengineering system, even if there is no one who
understands the state information of the entire system.
In other words, it is a prospective attempt to create anengineering system that replicates the order assumed toindicate the presence of God.
Of course, we cannot create a complete answer withregard to these characteristics since the natural
mechanisms are not completely understood. However,since our purpose is not to understand nature but tocreate engineering systems that replicate its
characteristics, we should assess our current
understandings in terms of their usefulness in systems
engineering. My current research activities consider thefollowing two characteristics.
 Action through a medium (Local interaction)
In physical systems, there are two concepts that
describe the interactions that can occur between
two objects in spatially different locations; action
at a distance and action through a medium (local
interaction). The former yields a model in which
two widely-separated objects interact directly. The
latter does not permit the existence of directinteraction between widely-separated objects; itassumes that interaction occurs only between
spatially adjacent objects, and the effect ofinteraction is incrementally exchanged between
the objects. Modern physics supports the actionthrough-a-medium concept, so interaction occurs
locally. In such a model, space is filled withphysical quantities at all points (which forms afield), and any variation in the physical quantity ata point propagates through the field at a finite
speed.
 Renormalizability (Reducing the degrees of
freedom in dynamics)
When attempting to observe a massive
aggregation of extremely small objects thatinteract in complex ways, we can more easily
comprehend the aggregate (or system) byreducing either the temporal or spatial resolution(or both), i.e., coarse-graining the system. In therenormalization theory, complex systems areunderstood by observing changes in ameasurable attribute identified by the coarsegrain transformation. The coarse graintransformation of observations is called
renormalization. We consider a system thatexhibits large (or infinite) degrees of freedom at
the microscopic scale. If the system is welldescribed by small (or finite) degrees of freedom
at the macroscopic (measurable) scale throughrenormalization,thesystemiscalledrenormalizable.
In the action-through-a-medium concept, an object
interacts only with its neighbors, at any instant. In theworld of action at a distance, changes in or by an object
instantly influence all places, including the end of theuniverse, and conversely, the changes of any object,regardless of its location, instantly influence the object.
6

In this situation, the components of reality areassociated with each other very strongly, which might
limit the flexibility of the world. Therefore, the actionthrough-a-medium concept appears to be a key
characteristic in producing stable systems while also
ensuring the freedom of local action.
Even if we do not fully comprehend the attributes of
micro-components such as atoms or we do notunderstand the complete mechanisms of nature, we canadmire the orderly behavior of the world. This meansthat even if there are huge degrees of freedom when theworld is observed at the micro-scale, almost all degrees
of freedom are missing at the macro-scale of humanperception, and only a small number of macroparameters are needed to describe the world. Thisconfirms the renormalizability of the world.
Based on these ideas, my research activities havebeen considering a hierarchical model based on
temporal and spatial scales as a framework for
information network control technologies. At eachlayer, the hierarchical model considers local
interactions on the temporal and spatial scales thatcharacterize the layer. The rules that describe local
interactions are described by a partial differential
equation, and the resulting overall system state is thesolution of the partial differential equation. In otherwords, a macro-scale state is realized as a solution of apartial differential equation by the micro-scale action
rule given as a local interaction. What kind of effectoccursbetweendifferent
layersinvolves
renormalization from the perspective of how coarsegrained the observations are.
3. User Dynamics and Relativistic Quantum
Mechanics
Imagine if there is any object in the world that does
not interact with others, can it be said that it reallyexists? Since it does not interact with light, it does notreflect light and is therefore invisible. Since it escapes
gravity, it must have no mass, and of course, it escapes
the sense of touch. Even if such a thing exists, isn't it
the same as not existing? From that point of view, it
can be seen that real existence is a concept based oninteraction with others. Then, what are the uniqueproperties possessed by objects that actually exist? For
example, attributes of the object itself, such as its color
being red, are recognized only when there is anotherobject that permits comparison, so it is also a conceptthat is based on mutual relationships. The real objects
themselves and their interrelationships are inseparable,
and they together make up this world. In therelationship between the characteristics of the “object”
itself that really exists and the “environment” createdby the interaction with others, we can recognize that
their boundaries are ambiguous. If we consider thiswhole and inseparable world as a network, our world isthe network itself.
A network that represents the relationship between
people through an information network is called an
online social network (OSN). Due to the rapid

[From CS Fellows]

IEICE Communications Society – GLOBAL NEWSLETTER Vol. 44, No. 4

development and spread of ICT in recent years,
communication between people has been dramatically
activated, and the ability to transmit information
generated by individuals has been strengthened; thishas greatly stimulated the activities of users in OSNs.
Therefore, understanding user dynamics in OSNs havebecome a significant issue. In my research activities,
the oscillation model was proposed to describe the user
dynamics in OSN; it is formulated as a wave equationon the network. In research on wired networks, thefirst-order differential equations with respect to time,such as Markov chains, are often used, but secondorder differential equations with respect to time, suchas the wave equation, are rarely used. The reasons why
my research uses the wave equation for modeling user
dynamics are as follows. The strength of the user's
activity influences the strength of the activity of otherusers via the OSN, but the influence does not spread
instantaneously, rather it propagates across the OSN ata finite speed. The wave equation describes thecharacteristics of propagation in a medium at a finite
velocity. For example, consider a function that
expresses the effect of influence propagation amongusers. If the effect propagates at a finite speed, then thetrigonometricfunctionsyieldedby
Fouriertransformation also move at the same speed. With
regard to the trigonometric function at each frequency,
if the movement is observed at a fixed point, it appears
to be oscillating. In other words, behind thephenomenon of propagation at a finite velocity, astructure that instantiates wave propagation isnecessary. The oscillation model was introduced for apurely theoretical reason following this background,but the oscillation energy is related to node centrality, aconcept often used in conventional network analysis.
For example, under the condition of uniform OSN use,
if all link weights are one, the oscillation energy of anode represents its degree centrality, and if the linkweight is the amount of traffic passing through the link,
the oscillation energy of the node represents its
betweenness centrality. Furthermore, oscillation energy
may diverge depending on the structure of the network,
which is considered to represent the situations in which
the intensity of user dynamics activity diverges, such as
the flaming phenomenon.
The oscillation model enables us to understand therelationship between user dynamics and network
structure. Thus, the oscillation model has the potential
to yield countermeasures to explosive user dynamics,
including flaming, such as altering the network
structure. In this situation, don't you want to understand the causal relationship between the kind of OSN
structure and the type of user dynamics evidenced by
the structure? The wave equation that describes user
dynamics is a second-order differential equation withrespect to time. Note that the first-order differential
equation with respect to time is essential here as it can
explicitly describe the causal relationship between the
network structure and user dynamics. Of course, its
solution must describe propagation at a finite velocity

so that it must also be a solution to the original wave
equation. If the equations that satisfy both requirements
are created, the OSN structure will not be conserved,
and problems will arise in which all users all over theworld will be directly linked to each other. Therefore,
in addition to the above requirements, we must find an
equation that completely conserves the OSN link
structure. The literature [5] (also [1] in Japanese) has
succeeded in giving a fundamental equation thatsatisfies all of the above requirements. Interestingly
enough, the fundamental equations of user dynamics
thus obtained have the same structure as the Diracequation that appears in relativistic quantum mechanics.
Here, relativistic quantum mechanics is a fundamental
theory of physics that combines special relativity andquantum mechanics and is the starting point of
quantum field theory. From this, the user dynamics aredescribed by the wave function that is quantized by the
anticommutation relations yielded by fermionic fields.
Note that the research did not artificially apply theequations of physics to describe user dynamics. The
fundamental equation of user dynamics is naturally
obtained from the goal of explicitly describing thecausal relationship of the network structure andconservation of the OSN link structure. Quantum
theory often details a mysterious world that differsfrom the real world, such as Schrödinger's cat, often
mentioned in public awareness books. However, thefindings obtained from the fundamental equations ofuser dynamics suggest that the framework of quantum
theory is not unique to the microscopic world, butinstead is inherent in the description of causal
relationships.
In quantum theory, there are several mathematicallyequivalent formulations, depending on the temporalchanges in the linear operator and/or the state vector
appearing in the equation. The formulation in which
the linear operator evolves with time is called theHeisenberg picture, the formulation in which the statevector changes over time is called the Schrödinger
picture, and the formulation in which both change overtime is called the interaction picture. In the fundamental
equation of user dynamics, the linear operator is amatrix that represents the network structure, and thestate vector is the state of the user. Therefore, the time
evolution of the linear operator is the change of therelation between the users, that is, the environmentchanges and the time evolution of the state vector is thetime change of the user's state. Since there are multiple
mathematically equivalent expressions depending on
which one changes over time, it can be recognized that
there are various views on whether the user's state is hisor her personality or is created from the environment.
As stated at the beginning of this section, this meansthat the user and the environment are inseparable.
4. Conclusions
This essay has introduced some of the concepts I
have become aware of in my daily research activities.
Although these are rarely stated explicitly in research7

New Stage of Radar Signal Processing:with my research experience in radar and remotesensing
Hiroyoshi Yamada
Faculty of Engineering, Niigata University
1. Introduction
It is a great honor for me to have been awarded the
IEICE fellow for my contribution on Application of
Array Signal Processing to Array Antenna and Radar
Remote Sensing. Most of all the results were obtained
via joint research collaborated with colleagues andstudents in my laboratory. I express my deepest thanks
for their cooperation.
My research carrier has started at antenna laboratory
in late ‘80s at Hokkaido University, Japan. It was atime to dawn the Internet at Universities in Japan. The
development of computer systems had brought about
revolutionary changes in measurement in the radio field
as well. I met a brand-new Network analyzer at thelaboratory, which bring me to the array signal
processing field.
2. Antenna Measurements with Network Analyzer
As many of you know that the network analyzer is afundamental measurement equipment for frequency
characteristics of microwave components such asantennas and circuits. The network analyzer appearedin late ‘80s could bring us many frequency sampled
data, or array data, easily. On the other hand, researchon high-resolution array signal processing was also
very active, and many algorithms were proposed suchas Capon, MUSIC, ESPRIT and so forth. Thesealgorithms are focused on Direction-of-Arrival (DOA)
estimation by using array antenna. Beamwidth of array
antenna can be determined by the aperture size, or
length of the array, then large antenna should be
required to realize high angular resolution. Abovealgorithm realizes super-resolution property beyond
beamwidth limit by solving the following equation:=r As + n ,(1)

where r is a column vector whose elements are thereceived signal by the array antenna. A is a matrix
whose columns contain the mode vector of incident
waves, and s is a vector whose elements corresponds
to the complex amplitude of each waves. The vector n
is the additive noise vector. The unknown parameters
to be solved in the above equation is DOA andcomplex amplitude of each incident wave. This
problem can be solved when the number of incident
waves are less than the number of array elements. Notethat resolution limit does not depend on the beamwidth

in this concept. The so-called superresolution
techniques, such as MUSIC and ESPRIT, utilize
second-order statistics property of signal and noise,then we can improve resolution performance inaccordance with increasing the number of snapshots.
Let’s get back to my first research. Equation (1)appears in many problems. We focused on an analogy
between received data vector of array antenna (spatial
domain data) and network analyzer (frequency domaindata).
We first demonstrated multiple reflection
detection in the microwave circuits with narrow
bandwidth data by using the MUISC algorithm [1].
The algorithm was also applied to the multipath
reflection detection and rejection in the antenna gain
[2] and pattern measurements [3]. In the microwave
measurements, precise calibration can be done andavailable frequency bandwidth is often limited, then the
superresolution technique becomes a powerful tool todetect multiple components and extract desired
components.
After my Ph.D. research, I have been working at
Niigata University where I had collaborated with Prof.
Yamaguchi who is one of the leading researchers inradar polarimetry. For the DOA estimation of multipath
waves with an array, decorrelation preprocessing
should be required to attain high-resolution estimation.
Polarization is one of the key properties in wave
propagation. I found that the arrays having different, ororthogonal, polarization can be effective as subarrays
to enhance decorrelation performance for distinct
polarization incidences [4]. In addition, antenna array
calibration is also very important to realize highresolution DOA estimation by using superresolution
techniques. There were many researches for calibration.
However, most researches focused on antennas. In
actual systems, not only element imbalance and mutual
coupling but also coupling between array and adjacentobjects often affected. These effects can also bemodeled to add virtual elements and coupling
coefficients among them. I modified the model in (1)and derive the algorithm [5, 6]. This idea leads tovirtual array for MIMO radar later.
3. Application to SAR Image Analysis
In late ‘90s, I had a chance to join the Jet Propulsion
Laboratory, NASA, as a visiting scholar for one year,
where I devoted in polarimetric Synthetic Aperture

Radar (PolSAR) image analysis. In the PolSAR
analysis we obtain the images by combination ofhorizontal and vertical transmission and reception.
SAR Interferometry is a technique to estimate height of
the terrain/targets by using a pair of SAR images.
In this problem, we find many problems shown in (1)[7-9]. I have struggled with polarimetric SARinterferometry, which is combination of PolSAR andinterferometry, to discriminate mixture of reflection
waves in small area. For example, in forest observationby using Interferometry at L-band, we have a problem
because part of transmitting wave is reflected bycanopy and the rest is reflected by the ground. I got an
idea to use polarimetry and a superresolution techniqueto solve the problem,that is array data in (1) can bearranged by the combination of PolSAR images and apair of data as a doublet for ESPRIT algorithm. Figure
1 shows an example of the results [7, 8]. This results
are the start point for high-resolution 3D SAR image
reconstruction reported in [10].
4. High-resolution Radar Imaging
Although the superresolution technique is a powerfultool for radar and remote sensing, high-resolution
property deteriorates for distributed scatterings. In sucha case, we should increase array aperture by adding
elements. That is costly. Next problem is how we cansolve the problem without increasing actual elements.
Here comes the virtual array concept again. I employed
Khatri-Rao matrix product virtual array technique for
the Ocean Surface Current Radar to improve angularresolution, which makes original array aperture almost
doubled [11].
From 2010s, MIMO (Multiple-Input MultipleOutput) technique has been actively introduced insensing. MIMO itself is a kind of virtual array
technique to realize N × M elements with N
transmitting and M receiving elements. We began toFig. 3 Number of effective elements for two
transmission elements in each MIMO virtual array
technique.
start developing MIMO radar for human detection andtracking at ISM band in early 2010s. The first system
had only two transmission and three reception. Angularresolution of the system was not satisfactory even when
we apply the MIMO. For uncorrelated targets, theKhari-Rao virtual array technique in [11] is available
for passive arrays. Since human motion arises diverse
Doppler, the reflected waves have low correlation. We
have modified the Khari-Rao virtual array techniquefor MIMO radar to enhance effective aperture [12-15].
Figure 2 shows an example of indoor human detection(two persons) by using conventional MIMO and the
proposed virtual array techniques. In addition, numberof effective elements with two transmitting antennas by
the technique is shown in Fig. 3. See [14] for the details.

system, we can easily obtain a MW-MIMO radar.
Researches on application of MIMO radar have been
activated. Since micro Doppler by human motion
becomes larger in MW radar, the virtual array
technique works more effectively [15].
To realize high-resolution imaging radar, SAR for
MW Radar is another solution. When we apply the
SAR with squint looking MW radar on automobile, 2D
imaging can be realized [16]. Figure 4 shows anexample of the real-aperture (w/o SAR processing) andSAR imaging results. It will bring us important
information that complements the shortcomings of
optical camera and LiDAR.
5. Conclusions
I reviewed my almost 30-year research work for arraysignal processing for antennas and radars. In early radar
research, improvement of detection performance was
the most important issue. This may say detection stage.
The superresolution technique by using second-order
statistics property of targets realizes not only highdetection performance independent of SNR but alsohigh resolution estimation. We have been struggling to
get better performance beyond the physical limit suchas SNR, bandwidth, array elements, and so forth. Deepunderstandings for physical characteristics of waves is
the key to create effective signal processing techniqueto exceed the limit. We may say this is estimation stage.
Now is the stage of recognition. We can obtain highresolution 2D/3D target images showing spatial
distribution of targets. In addition, time series of theimages, or Doppler history, bring us motion
information. These features can realize advanced target
recognition and classification. Machine learning is
accelerating researches in this field. This is the new Era
for sensing. I expect that new sensing applications will
be cultivated by the fusion of researchers in various
fields.

Cross-disciplinary Research on Cooperation in
Heterogeneous Networks

1. Introduction
It is a great honor to write this article as a new fellowof IEICE. I was awarded a fellowship from IEICE on
March 19th, 2020 for my cross-disciplinary research oncooperation in heterogeneous networks. In this article, I
will summarize my awarded research and how it will
impact the future.
2. Heterogeneous Networks
Heterogeneous networks are beneficial thanks to thediversity of nodes. As Fig. 1 (a) shows, if two nodes
have different connectivity, they might help each otherto satisfy a requirement in terms of communication
speed and range [1]. In Fig. 1 (b), one node has a richcommunication resource and the other has a richcomputing resource, so they might integrate theirresources to satisfy the application requirement [2].
Thus, nodes in a heterogeneous network could produce
a kind of “gain” from their diversity throughcooperation. However, compared with homogeneous
networks, it is not easy to operate heterogeneous
networks optimally and efficiently because we need tohandle different kinds of devices. In addition, ownersof those devices might also be heterogeneous andfurther complicate the operation of heterogeneous
networks if they behave selfishly.
3. Incentive Mechanism for Cooperation in
Heterogeneous networks
As the author mentioned, a single owner does notoperate all the nodes in a heterogeneous network, so
cooperation between nodes is essential for optimal andefficient operation. Figure 2 illustrates an incentive
mechanism for cooperation [3,4]. First, basically, theutility achieved through cooperation must exceed thecost of motivating nodes to behave cooperatively.
However, since this is not always guaranteed, incentive
rewarding must be introduced to keep the utility andthe given reward greater than the cost of establishingcooperation.
4. Approaches to Solving Cooperation Problems in
Heterogeneous Networks
To satisfy the condition to establish cooperation in aheterogeneous network (see previous section), theauthor came up with several solutions, categorized into
four approaches: cost model, utility model, incentive
rewarding methods, and cooperation optimality and12efficiency. The first approach is modeling thecooperation cost to reduce the overall cost. It is widely
known that individuals behave altruistically for thosethey are socially close to. Inspired by this, the author
proposes reducing the psychological cost ofcooperation by forming networks based on social
relationships [5–7]. The second approach is modelingthe utility of cooperation. Although delaying
communication requests and moving to a better
communication area contribute to offloading in heavily
loaded networks [8–11], unfortunately, the benefits forthe contributors themselves are indirect and implicit.
We need to design the system so that benefits fromcooperation become more direct and explicit toencourage cooperation. The third approach isrewarding incentives. Although monetary rewarding is
a straightforward way, managing both real and virtual
currency is too complicated. Therefore, instead of amonetary reward, the author proposed ways incentive
rewarding is achieved in each communication layerfrom physical to application. In wireless relay networks,
nodes that relay data to other nodes can obtain
additional bandwidth for their own transmission, which
incentivizes nodes to cooperate (Fig. 3) [12]. This idea
can be implemented in the physical layer [12], theMAC layer [13], the network layer [14], and thetransport layer [15]. In the application layer, gifting
additional content with no charge can be a good reward
for forwarding content to other nodes in content
delivery networks [16]. The fourth approach isensuring the optimality and efficiency of cooperation.
Methodologies from economics such as game theory
effectively model and solve the problem formulation[12,14].
5. Conclusion and Future Direction
Before 2000, only servers and personal computerswere connected via networks. Around 2005, manykinds of smart devices were connected. Now, in theInternet of Things era, nodes are becoming morediverse in networks day by day. The approaches tocooperation in heterogeneous networks introduced inthis article will help researchers and engineers design
heterogeneous networks optimally and efficiently.
Furthermore, these approaches will be broadly
applicable to other fields, such as human-machine
cooperation.

1. Introduction
The 2020 IEICE Society Conference was held online
September 15-18, 2020, where four Societies of IEICE,
Engineering Sciences Society (ESS), Nonlinear Theory
and Its Applications Society (NLS), Communications
Society (CS), and Electronics Society (ES), joined.
In the Conference, the IEICE Technical Committee
on Information Communication Management (ICM) [1]hosted a full English Session entitled “Network andService Design, Control and Management” as one ofeight Symposium Sessions which focused on special
topics of advanced technologies.
2. Background of ICM English Session
ICM has been hosting English session every year
since 2004. The purpose of this English session is tocontribute to the globalization of IEICE by offering thechance of the presentation and discussion in English to
the foreign researchers/students living in Japan and theoverseas researchers/students.
Figure 1 shows the change in the number ofcontribution papers since 2004. When the session
began in 2004, only 15 papers were submitted. Since
then, the number of papers has gradually increased, andit reached 55 papers in 2013. But this year, because of
the large negative impact of COVID-19, 13 papers
were posted.
The holding period of the session in the 2004 was
one and half days, and that in this year was two days.

1. Introduction
The Optical Fiber Technologies (OFT) committee,
which was established in April 1998, is one of thetechnical committees of the Communications Societyof the IEICE. One of the most important aims of ourcommittee is to contribute to technological innovationin relation to optical fiber technologies for thedevelopment of industrial applications. We do this byfocusing on the technologies from cross-sector
viewpoints with reference to communicationengineering, measurement technologies, optical devices,and materials. When OFT committee was established,
optical fiber was applied in practical use. Since then,there is a great interest in optical fiber application suchas sensing, signal processing, energy transport and theprogress in the study is expected in the future.
Our topics of interest mainly include optical fiber
sensing, optical fiber devices, optical fiber systems,
optical fiber wiring/installation, maintenance/operation,and the design of optical fiber/cables. We discuss
optical devices that are applied to actual
communication equipment. OFT covers research areas
ranging from basic optical technology to actual
maintenance.

1. Introduction
Workshop on Information Centric Networking
Solutions for Real-world Applications (ICN-SRA) was
held in conjunction with IEEE International Conference
on Communications (ICC) scheduled from 7th to 11th ofJune 2020. ICN-SRA was organized with support fromIEICE Technical Committee on Information Centric
Networking. The conference was originally planned tobe held in Dublin, Ireland. Due to COVID-19
pandemic, the entire ICC conference was organized in
virtual format. In particular, ICN-SRA was held in “ondemand” format throughout the conference period, i.e.,
ICN-SRA on-demand presentations were madeviewable from June 7th to 11th. The authors prepared
their presentation videos, and the videos were madeviewable at the conference web site during the period.
This ICN-SRA was the fourth reincarnation of theseries. The focus of the workshop is research,development, and evaluation of Information Centric
Networking (ICN) architecture and technology in realworld applications. ICN is now deployable thanks to
implementations such as NFD (Named Data
Networking (NDN) [1] Forwarding Daemon), Cefore[2], and CICN [3], and is ready to be used for realworld applications. The workshop targeted to provide aforum for researchers from both academia and industry
to demonstrate their recent progress in applying ICN intheir problem space as well as identify newopportunities and research gaps.
Sixteen manuscripts were submitted, and eightexcellent papers were selected for presentation in theworkshop.
2. Program
Due to on-demand format, only paper presentations
were scheduled. The presented papers were as follows.
 Enabling Named Data Networking Forwarderto Work Out-of-the-box at Edge Networks:
Self-configuration mechanism for edge network
forwarding plane in NDN was proposed. The
mechanism was implemented in NFD.
 Next-Generation Networking and Edge
Computing for Mixed Reality Real-TimeInteractive Systems: The challenges in
networking for AR/VR applications are discussed
based on analysis of AR/VR network interactions
and community survey among AR/VR researchers.
Also, an NDN-based framework to address thechallenges is proposed.

18

 Context-based forwarding for mobile ICNs: A
context-based packet forwarding strategy,
exploiting content names and network condition
surrounding routers, is proposed to deliver urgent
information as well as non-urgent information.
 NDNViber: Vibration-Assisted Automated
Bootstrapping of IoT Devices: NDNViber whichconveys secret information to establish securecommunication channel between IoT devices anda controller using vibration as the communication
media and NDN protocol is proposed.
 Leveraging Named Data Networking for
Industrial Automation: Opportunities andChallenges: Application of NDN to industrial
automation and control systems is explored andthe opportunities and challenges for future
research is discussed.
 NDNconf: Network Management Framework
for Named Data Networking: A management
framework and protocol for NDN is proposed.
The management framework is an adaptation andextension of NDNCONF.
 Rapid Establishment of Transient Trust for
NDN-Based Vehicular Networks: Application of
Swift Trust model to NDN-base vehicular network
is explored.
 Supporting Delay Tolerant Networking: A
Comparative Study of Epidemic Routing and
NDN: Epidemic Routing and NDN are comparedin terms of Delay Tolerant Networking support.
Simulation results show how the design
differences lead to different functionalities andprotocol performance.
3. Conclusion
It is pity for not being able to hold face-to-face
discussions among researchers in the developing field
like ICN. We are hoping to have another workshop
face-to-face in a near future. Please join us to discuss
networking of the future at the next workshop.

Report on the 2020 IEEE Summer Topicals
Meeting Series:
Space Division Multiplexing
Werner Klaus and Georg Rademacher
National Institute of Information and Communications Technology(NICT)
1. Introduction
The IEEE Summer Topicals Meeting Series[www.ieee-sum.org] is held annually in July and serves
as an international forum to facilitate informationexchange between various technical communities
working in rapidly growing areas of technology or on
emerging topics related to the general field of
Photonics. This year’s conference was supposed to beheld in the city of Cabo San Lucas in Mexico from July
13th to 15th, however, due to the outbreak of Covid-19,
took place in an all-virtual format on the same dates.
Historically, the conference hosts 4-7 topics that areproposed by international researchers who also work as
topic (co-)chairs if the topic is adopted for the
conference. Besides accepting contributed papers, thechairs invite some 20-30 world-renowned experts topresent the latest advancements and research results in
the respective field. This year’s topics were: Coherent Optics for Short Reach Network Signal Reconstruction Using Photonics
 Silicon Integrated Mid-Infrared Photonics
 Space Division Multiplexing
 Structured Light Interaction with Matter and theEnvironment
The topical on Space Division Multiplexing wastechnically co-sponsored by the IEICE TechnicalCommittee on Extremely Advanced Transmission
Technologies (EXAT). Due to the special circumstances
and the all-virtual format, registration to the conference
was free of charge resulting in an unprecedented highnumber of both total registrations of over 860 andaverage attendance per technical session of around 70.
2. BackgroundSpace division multiplexing (SDM) is seen as apromising solution to overcome the capacity limit of
the single-mode fibers used in today’s optical networks.
Research in this field aims at exploiting spatial
diversity in optical transceivers, fibers, amplifiers, etc.
to increase transmission capacity whilst reducing cost,complexity and energy consumption. Intensive researchcarried out over the past decade has brought forthsophisticated multi-core/multi-mode fiber designs andnovel transmission techniques constantly pushing thelimits on achievable data rates and spectral efficiency
with regard to a single strand of fiber. Recently, efforts
are also under way in taking SDM out of the laboratory
and bringing it closer to its adoption in commercial
systems.
20

3. Outline of the SDM topicalThe goal of this year’s SDM topical was threefold:(1) gaining an overview of the state of the art on SDM
fibers, devices and systems; (2) stimulating discussions
on the challenges that lie ahead for developing anddeploying massive parallel transmission systems; and(3) exploring applications of SDM technologies in
optics-related research areas other than fiber-optics
communications. To achieve this goal, the co-chairs Dr.
Georg Rademacher (NICT), Prof. Cristian Antonelli(Univ. L’Aquila) and Dr. Roland Ryf (Nokia Bell Labs)
put together a total of 11 exciting 1.5-hour technicalsessions over the three days. The sessions comprised 2
tutorials, 23 invited presentations and 3 contributed talks
covering areas such the techno-economics as well as
nonlinear and quantum properties of SDM fibers, SDM
transceivers, amplifiers and networks as well as signal
processing and free-space communications. The invited
speakers included, among others, Dr. Itsuro Morita(KDDI Research, incumbent chair of EXAT) who
presented the latest research activities within the EXAT
initiative with a focus on EXAT’s Roadmap ver.2 thatwas released earlier this summer, Prof. Masahiko Jinno(Kagawa Univ.), a world-leading expert on SDM
networks, and Dr. Hitoshi Takeshita (NEC) who has
been developing efficient multi-core fiber amplifiers.
Furthermore, Prof. Kunimasa Saitoh (Hokkaido Univ.)and Dr. Tetsuya Hayashi (Sumitomo Elec.) presented
some new insights on the design of randomly-coupledmulti-core fibers and experimental measurements on
the first field-deployed multi-core fibers. In the first
tutorial Prof. Siddharth Ramachandran (Boston
University) gave a comprehensive overview on orbital
angular momentum modes in optical fibers and how
these can be used in telecom and sensing applications.
In the second tutorial, Dr. Nicolas Fontaine (Nokia BellLabs) introduced the latest multimode technologies
being employed for free-space communications.
4. Conclusion
Owing to the effort of all speakers preparing
presentations of outstanding quality despite theworldwide pandemic, and the possibility to attend theconference for free from anywhere in the world, theSDM topical of the IEEE Summer Topicals 2020
Meeting closed with great success offering ample
opportunity for learning as well as exchanging ideas on
cutting-edge SDM technologies and the future of opticalcommunications.

Special Section on Dynamic Spectrum Sharing for Future Wireless Systems
The IEICE Transactions on Communications announces that it will publish a special section entitled “Dynamic Spectrum Sharing for Future
Wireless Systems” in the October 2021 issue.
To satisfy increasing demands for wireless communications as infrastructure of IoT, flexible operation of variety of wireless systems is necessary.
New wireless systems, such as 5G, support detailed management of radio resources in frequency and time domains. Some of such systems
downscale the cell sizes which consequently increases the number of base stations and requires allocation of more frequency. On the other hand,self-operation of wireless systems is recently getting attracted along with the diversification of use cases for wireless communications. For the
future of wireless communications, the way to secure more radio resources and utilize them flexibly are the key issue. One of the solutions isdynamic spectrum sharing (DSS), where vacancy of frequency is identified by sensing and database analysis so that other wireless system reuses
the frequency. Since R&D activities and experimental demonstrations are now ongoing in the world to establish the technologies including radio
regulations, it is the best opportunity at this point of time to share the research results on DSS, investigate its feasibility widely and look for further
academic issues. For these reasons, a special section on DSS was planned scheduled to appear in the October 2021 issue.

1. Scope
This special section aims at timely dissemination of research in these areas. Possible topics include, but are not limited to:(1) Principle theories and their application to DSS (Architectural concept, Machine learning, Artificial intelligence)(2) Sensing technologies of DSS (Distributed sensing, System recognition, Direction measurement, Monitoring system)(3) Radio database management of DSS (Radio resource management, Radio database management, Radio environment recognition,
Interference control, Transmission power control)(4) Radio system and operation for DSS (Dynamic spectrum access, Software defined radio, Spectrum shaping, Traffic control, Beam-forming,
Interference cancellation, NOMA, Self organized networks, Local 5G, Massive MIMO)(5) Experimental demonstration of DSS (Feasibility experiment, Field test, Application to 5G, Experimental testbed)
A submitted paper should be related to DSS. Otherwise, the editorial committee decides it as out of scope in this special section.

2. Submission Instructions
The standard number of pages is 8. The page charges are considerably higher for extra pages. Manuscripts should be prepared according to theguideline in the "Information for Authors." The latest version is available at the web site, https://www.ieice.org/eng/shiori/mokuji_cs.html. The
term for revising the manuscript after acknowledgement of conditional acceptance for this special section could be shorter than that for regularissues (60 days) because of the tight review schedule.
This special section will accept papers only by electronic submission. Submit a manuscript and electronic source files (LaTeX/Word files, figures,
authors’ photos and biographies) via the IEICE Web site https://review.ieice.org/regist/regist_baseinfo_e.aspx by November 2, 2020 (JST).
