Patil College of Engg. & Technology, Kolhapur, Maharashtra, India Abstract A very promising approach for various wireless applications to use multiple antennas at both the transmitter and the receiver. The error rate performance and complexity of the algorithms are evaluated for different antenna configurations, for various constellation sizes, for different channel properties with and without coding. It is shown that Maximum Likelihood Detection (MLD) [1] outperforms the other schemes. Its complexity, however, is the highest and growing exponentially with the number of transmit antennas. Less complex alternatives are found that have only a slightly worse performance. Since V-BLAST techniques are simulated. It is shown that the maximum diversity gain equals the product of the number of transmit and receive antennas and the effective length of the channel impulse response. Introduction Recent research on wireless communication systems has shown that using multiple antennas at both transmitter and receiver offers the possibility of wireless communication at higher data rates compared to single antenna systems. The information-theoretic capacity of these multiple-input multiple-output (MIMO) channels was shown to grow linearly with the smaller of the numbers of transmit and receiver antennas in rich scattering environments, and at sufficiently high signal-to- noise (SNR) ratios. Some special detection algorithms have been proposed in order to exploit the high spectral capacity offered by MIMO channels. One of them is the V- BLAST (Vertical Bell-Labs Layered Space-Time) algorithm which uses a layered structure. This algorithm offers highly better error performance than conventional linear receivers and still has low complexity.
