Abstract

Abstract

V-BLAST receiver is effective technique in achieving high data rate in wireless communications. However, the complexity of V-BLAST is very high because much time must be consumed in performing linear nulling, successive interference canceling and sorting, and the application of V-BLAST is limited. The complexity of the ZF receiver and MMSE receiver is low, but performance is worse than V-BLAST. In this paper, a new layered space-time receiver is proposed using two stage successive interference canceling, and the complexity of new scheme is very low compared with the V-BLAST. The simulation results indicate that the performance of the proposed receiver based on MMSE is outperforms ZF V-BLAST receiver.
