MIMO Overview[1]-[3]
Future trend for wireless communications
Future wireless applications create insatiability B demand for “high data rate” and “high link quality” wireless access Spectrum has become a scarce and expensive resource B bandwidth is very limited Regulation, device and system capacity concerns B transmit power
