In this letter, we consider a transmit antenna selection scheme that provides selection diversity gain by exploiting a limited feedback information, and we propose a selection criterion appropriate for iterative receivers. Since the conventional selection criterion does not consider the convergence behavior of iterative receivers, a two-step antenna selection criterion is proposed, taking into account performance improvement as a function of iteration. Based on simulation results, the proposed scheme demonstrates superior performance compared to the conventional scheme as the number of iteration increases.
