PROJECT TITLE :

Throughput Analysis and Optimization of Wireless-Powered Multiple Antenna Full-Duplex Relay Systems

ABSTRACT:

We take into account a full-duplex (FD) decode-and-forward system in which the time-switching protocol is utilized by the multiantenna relay to receive energy from the supply and transmit info to the destination. The instantaneous throughput is maximized by optimizing receive and transmit beamformers at the relay and therefore the time-split parameter. We tend to study both optimum and suboptimum schemes. The reformulated downside within the optimum scheme achieves closed-type solutions in terms of transmit beamformer for a few eventualities. In different situations, the optimization drawback is formulated as a semidefinite relaxation problem and a rank-one optimum answer is often guaranteed. In the suboptimum schemes, the beamformers are obtained using maximum ratio combining, zero-forcing, and maximum ratio transmission. When beamformers have closed-kind solutions, the achievable instantaneous and delay-constrained throughput are analytically characterised. Our results reveal that beamforming increases both the energy harvesting and loop interference suppression capabilities at the FD relay. Moreover, simulation results demonstrate that the choice of the linear processing scheme as well as the time-split plays a essential role in determining the FD gains.
