Wireless communication system with multi-antenna arrays has been a field of intensive research on the last years. The emergence of multiple antenna system has opened another very resourceful dimension - space, for information transmission in the air. It has been demonstrated that multiple antenna system provides better BER and it can be further improved by using different modulation techniques. Since then, Multiple-Input Multiple-Output (MIMO) system has become one of the major focuses in the research community of wireless communications and information theory.
