Abstract

Group layered space-time architecture (GLST) which combines space-time block coding and layered space-time processing can achieve a good diversity-multiplexing tradeoff. For GLST, we present an antenna selection (AS) algorithm based on QR decomposition of the equivalent channel matrix. The presented AS algorithm can achieve excellent error rate performance for GLST with the QR decomposition-based successive interference cancellation receiver. Moreover, a fast AS algorithm with only a small loss in performance is considered.
