This paper investigates transmit antenna selection (TAS) to improve the secrecy performances in MIMO secure cooperative relay systems with an adaptive decode-and-forward (DF) relay over Nakagami-m fading channels. Due to the feedback delay of CSI used for TAS, the maximal ratio combining (MRC) receiver at the multi-antenna relay and destination suffers from the outdated channel state information (CSI). To evaluate the impacts of TAS with outdated CSI on the secrecy performance, the closed-form… CONTINUE READING
