“…In [25], it is shown that a MAMR network with single antenna source and destination can be transformed into a single antenna multiple relay (SAMR) network by performing Maximal Ratio Combining (MRC) at reception and transmission for each relay nodes. This enables the network beamforming introduced in [14] to be readily employed.…”

A multi-antenna multiple relay (MAMR) network is considered and a variation of two-hop zero-forcing amplify-forward relaying method is proposed. Deploying ZF method together with application of diagonal power allocation matrices at the relays, it is shown that the overall MAMR network is simplified to M independent single antenna multiple relay (SAMR) networks, where M is the number of source and destination antennas. This enables to incorporate network beamforming proposed for SAMR networks. Accordingly, using the BER as the performance metric, we present simulation results to show the proposed approach outperforms the common ZF method addressed in the literature
