Wireless communication system with multi-antenna arrays has been a field of intensive research on the last years. The use of multiple antennas at both the transmitter and the receiver sides can drastically improve the channel capacity and data rate. The paper of the performance limits of MIMO system becomes very important since it will give lot ideas in understanding and designing the practical MIMO systems. Vertical-Bell Laboratories Layered Space-Time (V-BLAST) architecture and first practical implementation of this architecture on MIMO wireless communications to demonstrate a spectral efficiency as high as 40bits/s/Hz in real time in the laboratory.
