Abstract

In this paper, half-and full-duplex relay processing matrices and source-destination beamforming vectors are jointly optimized based on a minimum mean-square-error (MMSE) formulation under inequality constraints on the transmit power of the source and the relays. Through BER simulations, we illustrate that the full-duplex method performs better than the half-duplex method in various signal-to-noise ratio (SNR) scenarios, and it can be a promising candidate for future relay networks.
