Abstract
Systems and techniques relating to wireless signal processing. A described technique includes receiving a signal, having subcarriers, over a wireless channel formed by a number-of-receive-antennas and a number-of-transmit-antennas; determining a signal quality measure of a received signal having subcarriers, the signal quality measure being based on channel gain matrices corresponding respectively to the subcarriers of the received signal, the channel gain matrices having dimensions of the number-of-receive-antennas by the number-of-transmit-antennas; determining a channel quality measure of the received signal that measures a frequency selectivity of the wireless channel; determining a data rate of information transmission over the wireless channel based on the signal quality measure and the channel quality measure, the signal quality measure serving as a primary determinant of the data rate and the channel quality measure serves as a secondary determinant of the data rate; and transmitting information over the wireless channel in accordance with the data rate.
