Abstract -As an important space-time code, V- BLAST (Vertical-Bell Lab Layered Space-Time) code has been studied recently. Zero-Forcing (ZF) and Minimum Mean Square Error (MMSE) are two nulling criteria that are commonly used in the V-BLAST system. In this paper, we propose the new detection algorithm for MMSE criterion that exterminates mutual interferences; hence the BER performance is improved. It can be done by modifying the channel matrix after each detection step. We also perform simulation to validate the analysis. Index Terms -V-BLAST, MIMO, MMSE, wireless communication
