Title: Demodulating apparatus of receiver
Inventor: MATSUDA SHOJI
IPC: H04L27/227
Filed: 1999-02-25
Abstract: The scale of circuit can be small. A demodulating circuit (1A) quadrature-detects a received signal generated by time-multiplexing digital signals which are respectively BPSK-, QPSK-, and 8PSK-demodulated. From the outputs I and Q of the demodulating circuit (1A), a timing circuit (30) detects a burst symbol signal interval. A pattern reproducing circuit (40) outputs the same PN code pattern as on the transmission side. Inverting circuits (13, 14) output RI and RQ on receiving I and Q respectively if the bit of the PN code pattern is "0" and output RI and RQ on receiving -I and -Q respectively if the bit is "1". In a phase error table (ISA) listed are the phase error between the phase at a received signal point and the absolute phase of each output of the inverting circuit (13, 14) for the first quadrant of RI and RQ. A phase error detecting circuit (16A) reads phase error data corresponding to the absolute values of RI and RQ and adjust the data to data according to the quadrants where RI and RQ are present. A carrier reproducing circuit (10A) corrects the phase of a reference carrier used for the quadrature detection so that the adjusted phase error data may be zero.

Title: Routing method for wireless and distributed systems
Inventor: LOHER URS
IPC: H04L12/56
Filed: 1998-11-10
Abstract: Method for routing packets (2) within a wireless telecommunication network (3), wherein the packets are transmitted from one source station (5) to at least one sink station (6) through a plurality of mobile relay stations (N i-1, N i, N i+1). The packets can be directly transmitted (108-110) through a wireless link (7) between neighbour mobile relay stations (N, N i-1, N i, N i+1). The routing of packets in the mobile relay stations (N i) is based on information autonomously monitored by this mobile relay station (N i) about its neighbour mo-bile relay stations (N, N i-1, N i+1). Each packet is routed in said mobile relay station (N i) to one, or more, next station(s) (N i+1) chosen from among the set of all of its neighbour mobile relay stations (N, N i-1, N i+1). Each packet (2) contains a header indicating the source station (5) which emitted the packet, at least one sink station (6) to which the packet is destined, and the neighbour mobile relay station (N i+1) to which said packet will be transmitted in the next hop. The indication of the next neighbour mobile relay station (N i+1) is replaced in each mobile relay station (N i). The choice (104) of the next station (N i+1) made from among the mobile relay stations (N i) depends on the distance between the next mobile relay station (N i+1) and the sink station (6). The position of the mobile relay stations (4, 5, 6, N, N i-1, N i, N i+1) may be determined by a positioning system, e.g., a GPS, in the mobile relay stations and communicated to all neighbour mobile relay stations.

Title: Road-based evaluation and interpolation of wireless network parameters
Inventor: CLARKSON KENNETH L
IPC: H04B7/26
Filed: 2000-10-24
Abstract: Techniques for determination of network parameters in, e.g., a processor-implemented system for characterizing, adjusting or optimizing the performance of a wireless network. In an illustrative embodiment, values of one or more link parameters of the wireless network are interpolated along edges in a mesh of data points derived at least in part from road location data characterizing an area serviced by the wireless network. A measure of network performance, e.g., a coverage measure based on pilot signal-to-interference ratio, may be generated using the interpolated values. The edges of the mesh have associated therewith a set of edge weights representative of traffic in the wireless network. The edge weights may be adjusted so as to be in agreement with available network traffic data. Interpolating between the data points of the road-based mesh permits the network performance measure to be computed as a smooth, differentiable function of the one or more link parameters, thereby simplifying network characterization, adjustment and optimization.

Filed: 2000-10-31
Abstract: In a replicated component system, changing the condition of a component can deleteriously effect the system as a whole unless the result of making such a change may have on other components is considered. In response to a request to change the condition of a subject component to a specified condition, where the request is from a fixed set of request operations, the request is first validated using a particular validation algorithm associated with the request type. If the request is successfully validated (i.e., a determination is made using the validation algorithm that making the requested change will not negatively affect the system or components with which the subject component has a relationship), then the request is realized using a particular realization algorithm associated with the request type. Each validation algorithm and realization algorithm are from fixed sets of such algorithms that are associated with each possible request operation. Prior to effecting a change to any component in the system, the configuration controller is provided with information that includes the type of component that each component in the system is and the relationships that exist between components. Such relationships are also from a fixed set of possible relationships. This information is provided through a graphical user interface in which the attributes of each component type and the relationships between components are specified using dialog windows and a canvas window which visually displays representations of each component in the system and the relationships that exist between these components.

Title: High capacity ultra-long haul dispersion and nonlinearity managed lightwave communication systems
Inventor: CAO XIANG-DONG
IPC: H04B10/18
Filed: 2001-03-01
Abstract: A transmitter terminal in an ultra-long haul optical transmission system receives separate channel input signals in separate ones of a plurality of return-to-zero transmitters (RZTX). Each RZTX generates a corresponding forward error correction (FEC) modulated output signal in a separate channel frequency sub-band including predetermined channel separations from adjacent channel frequency bands. A multiplexing arrangement multiplexes the plurality of channel frequency bands from the RZTXs into separate groups of frequency bands. The groups of frequency bands have predetermined band-gap separations therebetween, and each group of frequency bands has a predetermined separate pre-chirp introduced therein before being multiplexed with all other groups of frequency bands into a single multiplexed output signal. An optical transmission line (OTL) is subdivided into predetermined sections and receives the single multiplexed output signal. A separate Raman amplifier (RA) is located in each separate section of the OTL for providing backward distributed Raman amplification. A dispersion compensating line amplifier (DCLA) is located in predetermined space-apart sections of the OTL for introducing dispersion compensation for the single multiplexed output signal and each of the groups of frequency bands therein.
