The existing and emerging next generation of wireless communication standards assume that the end-users use omni-directional antennas, radiating in all directions. This has been a barrier to network capacity and efficiency. Multiple input multiple output (MIMO) is considered as a key smart-antenna technology, to improve the capacity of a communication channel at a greater extent as compared to single input single output (SISO) and single input multiple output (SIMO) techniques. MIMO is a technology which uses multiple antennas both at transmitter and receiver ends to increase the overall data...
