Abstract
This paper proposes two schemes, TAS-SD&RD and TAS-SR&RD, in which transmit antenna selection (TAS) strategies are combined with amplify-and-forward (AF) protocol in MIMO relaying scenario considering the destination has only limited channel state information (CSI) of the source-to-relay channel, and analyzes asymptotic performance of the two schemes. The source, destination, and relay are equipped with multiple antennas, denoted by N S, N D, and N R, respectively. Specifically, the paper derives the asymptotic outage probability and symbol error rate (SER) of the proposed schemes in the cooperative AF MIMO relaying scenario. These analyses in high SNR regime lead to the conclusion that TAS-SD&RD and TAS-SR&RD can achieve full diversity order, N S N D + NR min {N S,N D}, in some antenna configurations of the cooperative scenario. Numerical results that confirm our analyses are also presented in the paper.
