Abstract

In this article, we present different space-time receive processing techniques for frequency selective multiple input multiple output (MIMO) channels and evaluate their performance. We present the solutions for linear zero-forcing (ZF) and Wiener filter (WF) equalization with latency time optimization and incorporate the Bell Laboratories Layered Space Time (BLAST) architecture to gain diversity. Furthermore, we present systems based on decision feedback equalization (DFE). We also combine this equalization method with the BLAST principle.
