Review: Performance evolution of different detection techniques in V-BLAST

Multiple Input Multiple Output (MIMO) channels can offer high capacity to wireless systems and the capacity increases linearly with the number of antennas. There are many schemes that can be applied to MIMO systems such as space time block codes, space time trellis codes, and the Vertical Bell Labs Space-Time Architecture (V-BLAST). We study the general MIMO system, the general V-BLAST structure with Zero-Forcing (ZF) and Minimum Mean Square Estimation (MMSE) detectors. Based on bit error rate, we show the performance of these receiver schemes in flat fading channels in MatLab.
