For future wireless communications systems there is a greater empha-sis on providing higher data rates and improved quality in terms of reliability over multipath fading channels. Multiple Input Multiple Out-put (MIMO) communications systems has received enormous atten-tion recently, as they can provide a roughly linear increase in data rate by using multiple transmit and receive antennas. In a future where communication systems may implement MIMO technology, mobile user terminals are desired to be small, lightweight and have extended battery life. This is at odds with MIMO systems because...
