Abstract

We compare the outage performance by applying transmit antenna selection strategies to amplify-and-forward protocol in the MIMO relaying scenario. Although antenna selection is a suboptimal form of beamforming, it enjoys the advantages of tractable optimization and low feedback overhead. Specifically, by combining transmit antenna selection strategies with amplify-and-forward protocol, we propose two suboptimal strategies, TAS-SD&RD and TAS-SR&RD, and compare their performance with the optimal strategy, TAS-Optimal. By observation of simulation, the suboptimal strategy TAS-SD&RD can achieve the full diversity order with only a small performance loss compared with the optimal strategy TAS-Optimal in some antenna configuration scenarios.
