End-to-End BER Performance of Cooperative MIMO Transmission with Antenna Selection in Rayleigh Fading

Combining a dual-hop relaying with multi-input multi-output (MIMO) transmission is a natural way to overcome the channel impairments. The antenna selection is a simple but efficient MIMO method since it enjoys the full diversity with moderate channel state information (CSI) from the receiver and no complicated spatial coding. For amplify-and-forward (AF) MIMO relaying with best antenna selection, we derive the probability density function (PDF) of the received signal-to-noise ratio (SNR) and provide a BER equation when using M-ary PSK in Rayleigh fading channels.
