Title
BEAMFORMING FOR BIDIRECTIONAL MIMO FULL DUPLEX UNDER THE JOINT SUM POWER AND PER ANTENNA POWER CONSTRAINTS
Abstract
This paper considers a bidirectional (BD) full-duplex (BD-FD) communication system design under the joint sum-power and per-antenna power constraints. The sum-power constraints are naturally imposed by regulation to limit the total transmit power, and the per-antenna power constraints consider the physical limits of the power amplifiers (PAs). We propose a novel beamforming design to maximize the weighted sum-rate (WSR) with alternating optimization under the limited dynamic range (LDR) noise model. At each iteration, we use minorization-maximization approach to optimize the beamformers and power allocation. Simulation results show significant performance gain compared to a half-duplex BD system or FD system with only sum-power constraints. However, the gains are limited by the maximum of the thermal noise variance or the LDR noise variance.
