• W2894864561 abstract "This paper investigates wireless information and power transfer in a full-duplex MIMO relay channel where the self-sustained relay harvests energy from both source transmit signal and self-interference signal to decode and forward source information to a destination. We present a novel technique to jointly optimize power splitting at the relay and precoding design (power allocation) for both the source and relay transmissions. We formulate a new convex optimization problem, establish the dual problem via closed-form optimal primal solutions, and design an efficient primal-dual algorithm to maximize the achievable throughput. Numerical results demonstrate the benefits of using multiple transmit and receive antennas in both information decoding and energy harvesting. We also extend our analysis to the case when channel state information is only available at receiving nodes and show how our algorithm can optimize the power splitting at the relay for it to remain self-sustained. Through analysis and simulation, we show how an optimal combination of non-uniform power splitting, variable power allocation, and self-interference power harvesting effectively exploits a full-duplex MIMO system to achieve significant performance gains over existing uniform power splitting and half-duplex transmission techniques." @default.
