The next generation wireless communication systems are expected to support a wide range of high-quality services which require high data rate transmission as well as high system capacities. One of the most promising techniques for realizing extraordinary spectral efficiencies over wireless links is V-BLAST (Vertical-Bell Laboratories Layered Space-Time). This is a new system proposed by Bell Laboratories as an extremely efficient scheme for high capacity communications in wireless environments. The V-BLAST technique employs a multi-element antenna array technology at both the transmitter and receiver to increase system capacity, data rate as well as spectral efficiency. In this paper, and in contrast to previous work, we consider the performance of V-BLAST in a frequency selective fading channel. In particular, we investigate the effect of time delay spread on V-BLAST
