Patent ID: 8306000

Claim:
A method of optimizing a rank of a Minimum Mean Squared Error (MMSE) channel equalizer in a wireless receiver, the method comprising the steps of: transmitting negative acknowledge (NACK) and acknowledge (ACK) messages by the wireless receiver; calculating a number of ACK and NACK messages transmitted; calculating an estimator of a throughput of the MMSE channel equalizer; wherein the estimator is dependent on a number of NACK messages transmitted by the receiver; establishing a first and second thresholds for a percentage of NACK messages; adjusting the rank of the MMSE channel equalizer according to the throughput by increasing the rank if the percentage of NACK messages exceeds the first threshold; decreasing the rank if the percentage of NACK messages is less than the second threshold; and repeating the steps of adjusting and decreasing until the throughput of the MMSE channel equalizer equals a desired value.
