The use of multiple antennas for transmission and reception is a major technological advance that is expected to make it possible to increase the data rate in wireless networks by orders of magnitude. While the use of more than one antenna at the receiver side is quite common, only recently was a communication theory of multiple transmit and receive antenna developed. Equalizer design must typically balance Inter Symbol Interference mitigation with noise enhancement, since both the signal and the noise pass through the equalizer, which can increase the noise power. Moreover, equalizers require an estimate of the channel impulse or frequency response to mitigate the resulting Interference Symbol Interference. In this paper the performance comparison of Multiple Input Multiple Output Systems with different Zero Forcing Equalization Techniques using Binary Phase Shift Keying Modulation in Rayleigh Channel is provided.
