Abstract :
V-BLAST is a suboptimal algorithm that can reach a large fraction of its Shannon capacity under some proper propagation environments. In this paper, we first derive the realizable capacity equation of V-BLAST algorithm and then analyze the realizable capacity of V-BLAST algorithm when transmit antenna adaptive selection is used. It is shown that the largest realizable capacity of V-BLAST algorithm with transmit antenna adaptive selection, is generally different from the largest Shannon capacity for some range of signal-to-noise ratios and channel matrix condition number, furthermore, a large fraction of capacity of MIMO system can be obtained by transmit antenna adaptive selection.
