Recent research on wireless communication systems uses multiple antennas at both transmitters and receiver. It offers the possibility of wireless communication at higher data rates compared to single antenna systems. The information capacity of these Multiple-Input Multiple-Output (MIMO) channels grows linearly with smaller number of transmitter and receiver antennas in rich scattering environment. Some special detection algorithms have been proposed in order to exploit the high spectral capacity offered by MIMO channels. This magnitude of spectral efficiency is exploited using a wireless communication architecture known as the VBLAST (Vertical Bell Laboratory lAyered Space Time).
