Abstract :
In this paper, we evaluate the performance of lattice reduction (LR) scheme in a highly correlated (2,2) channel where the receiver uses zero forcing V-BLAST as a detection algorithm. We also examine the behavior of the V-BLAST scheme with and without lattice reduction processing by comparing their symbol error rate (SER) with those resulting from sphere decoding (SD) when there is a spatial correlation coefficient up to 0.8 among receive antennas.
