Reference number : GC-2017-Q1-01810, amendment number : , agreement type : G, recipient legal name : Yongacoglu, Abbas (University of Ottawa)|Yongacoglu, Abbas (Université d’Ottawa), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Discovery Grants Program - Individual, program name french : Programme de subventions à la découverte - individuelles, program purpose english : We propose to continue our ongoing research activities in the physical layer area of future wireless communications systems. We will investigate, design, analyze and evaluate enabling techniques that can contribute to the evolution of future wireless systems. We view our research efforts in 3 directions. 
Our first research topic focuses on modeling and performance evaluation of heterogeneous networks (HetNets) made up of macro and small cells. We are working on developing accurate user and base station distribution models that take into account propagation as well as user behavior related aspects. These models will allow us to calculate the capacity of different network configurations under varying interference, channel conditions, traffic density, etc. and to design practical and efficient transmission/reception techniques and resource allocation strategies. 
The second topic is concerned with the role of drone base stations (BSs) in cellular networks. Drones are low altitude unmanned aerial vehicles (UAV). Drone-BSs can serve mobile cells of any size and thus help the ground network of BSs in providing high data rate coverage whenever there is an excessive need in space and time, especially when this excessive demand occurs in a rather difficult-to-predict manner. By proper placement and networking of the drone base stations we will improve capacity, throughput, reliability and power consumption of the system. 
The third direction deals with various issues related with full-duplex (FD) systems. Until recently receiving and transmitting the signal at the same time interval and frequency band was not possible. Recent developments on antenna technology and signal processing techniques now make FD feasible. We are investigating different structures, i.e. relaying, network coding, relay selection, where FD can be beneficial and we are developing analytical tools for their system performance evaluations., program purpose french : We propose to continue our ongoing research activities in the physical layer area of future wireless communications systems.
