Abstract
BLAST, a MIMO wireless communication systems can achieve very high spectral efficiency in rich multipath environment through exploiting the extra space dimension. A simplified version of BLAST known as V-BLAST has been proposed and implemented. In this paper we compare the performance of various V-BLAST algorithms through computer simulations. The results show that the nonlinear detection schemes with interference cancellation (IC) have much better performance than linear detection schemes and Minimum Mean Squared Error schemes (MMSE) have better performance than Zero Forcing (ZF) schemes. The efficient square-root algorithm with IC shows very attractive property that having low complexity while keeping the good performance compared with conventional IC scheme. In our simulation, little improvement is observed for the Pre-match filtering plus IC scheme.
