BER Performance of Different Detection Schemes of V-BLAST

Multiple input multiple output (MIMO) techniques are expected to be widely employed in wireless communications to address the ever-increasing demand for capacity. MIMO systems provide a linear increase in capacity with the number of antenna elements, affording significant increase in capacity over single input single output (SISO) systems. In this paper, we discuss some of the most basic detection schemes of V-BLAST for wireless links with multiple antennas: M at the transmit site and N at the receive site and also discuss the architecture of V-BLAST techniques. In the simulation result we compare different detection techniques such as zero forcing (ZF), minimum mean square error (MMSE) and maximum-likelihood (ML) of
