Diversity Combining Techniques for FD AF MIMO Relays

We study a system with a full-duplex (FD) amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay and a single antenna at the source and the destination. The residual self-interference (RSI) is shown to behave as inter-symbol interference (ISI) at the destination. Assuming Rayleigh fading on all the channels, we derive the end-to-end impulse response and consider diversity combining schemes including Equal Gain Transmission (EGT),...
