PROJECT TITLE :
On the Rate Regions of Single-Channel and Multi-Channel Full-Duplex Links - 2018
ABSTRACT:
We tend to study the achievable rate regions of full-duplex links in the one- and multi-channel cases (in the latter case, the channels are assumed to be orthogonal, e.g., OFDM). We gift analytical results that characterize the uplink and downlink rate region and efficient algorithms for computing rate pairs at the region's boundary. We additionally give close to-optimal and heuristic algorithms that “convexify” the rate region when it is not convex. The convexified region corresponds to a combination of some full-duplex rates (i.e., to time sharing between totally different operation modes). The algorithms can be used for theoretical characterization of the speed region furthermore for resource (time, power, and channel) allocation with the objective of maximizing the sum of the rates when one of them (uplink or downlink) should be guaranteed (e.g., due to QoS considerations). We numerically illustrate the speed regions and the rate gains (compared with time division duplex) for various channel and cancellation eventualities. The analytical results provide insights into the properties of the full-duplex rate region and are essential for future development of scheduling, channel allocation, and power management algorithms.
