Diversity‐multiplexing tradeoff analysis in cooperative wireless networks with a multiple‐antenna relay

Performance analysis of sub‐optimal transmit and receive antenna selection amplify and forward cooperative communication

“…In an AF protocol, the relay simply amplifies the received signal and forwards it to destination [5,6]. Furthermore, the application of multiple-inputmultiple-output (MIMO) techniques to cooperative networks enhances the data rate and network reliability [7] while increasing network complexity due to the multiple radio-frequency (RF) chains as well as the overall cost in terms of size and power [8]. One attractive way to mitigate this requirement without degrading the performance is to use antenna selection (AS) technique, which is a sub-optimal form of beamforming [9][10][11].…”
