Performance Analysis of FD MIMO DF Cooperative Relaying Networks Using ZFBF

In this paper, we statistically analyze the performance of full-duplex (FD) MIMO decode-&-forward (DF) cooperative relaying networks. More specifically, we evaluate the end-to-end statistics under assumed system and channel models. Then, based on these results, we derive accurate closed-form expressions of the outage probability and the average bit error rate for both the transmit and the receive zero-forcing beamforming schemes in Rayleigh fading environments. Some selected results are presented to show some interesting observations useful for system designers. For instance, we find that the increased hardware complexity of DF relays is generally worth the high cost in FD relay scenarios, but not in half-duplex cases.
