Reduced Complexity Beamforming with Optimal Power Allocation in Two-Way Multi-Antenna Relay Systems

Abstract

This paper introduces a new beamforming method for a two-way relay system, where two single-antenna terminals exchange messages via a multi-antenna amplify-and-forward (AF) relay operating in the half-duplex mode. The optimization problem under consideration is to design a relay beamforming matrix that maximizes the achievable weighted sum rate under the… (More)
