Abstract:
Systems and methods for a downlink precode filter directed towards both wired and wireless MIMO communication systems. Systems and methods of the invention can provide close to optimal capacity (similar to the water-filling solution) while requiring power amplifiers associated with transmit antennas to operate at a fixed power level. In particular, systems and methods of this invention can improve the performance of MIMO wireless devices such as 802.11n, WiMax, LTE, LTE-Advanced etc.
