Numerous diversity techniques are used to minimize BER in wireless systems. But, the most effective diversity technique is space diversity. Space diversity is utilization of multiple antenna systems Multiple Input, Multiple Output (MIMO), which gives a significant enhancement to data rate and channel capacity. Multiple antenna technology can also be used to increase the data rate (spatial multiplexing) instead of improving robustness. Space diversity is used to overcome the effect of fading. In this paper, receive diversity is used i.e. using single antenna at transmitter side and multiple antennas at receiver side.
