Rate control technique for layered architectures with multiple transmit and receive antennas

Abstract From the Canadian patent

In a wireless communication system using multiple antennas at the transmitter and multiple antennas at the receiver with a sufficiently large , number of, antennas and/or diversity order the same performance that is obtainable when employing instantaneous rate indication feedback can be attained without any such, short-term feedback by adjusting the data rate of each transmit antenna according, to a prescribed function. The prescribed function does not depend on the shortterm state of the channel, but instead only depends on its long-term statistics. which may be fed back from the receiver to the transmitter at relatively lengthy, intervals.
