Patent ID: 7720184

Claim:
A method for reducing multipath distortion in a mobile FM receiver with a plurality of antennas, comprising the steps of: receiving a first antenna signal via a first antenna and a second antenna signal via a second antenna; weighting the first antenna signal with a variable first weight and the second antenna signal with a variable second weight; and combining the weighted first antenna signal with the weighted second antenna signal to provide a combined received signal having a combined signal level; wherein the variable first and second weight are determined by an adaptation strategy substantially controlled by a first algorithm when the combined signal level is greater than a predetermined signal level, and wherein the variable first and second weight are determined by the adaptation strategy substantially controlled by a second algorithm when the combined signal level is less than the predetermined signal level, and wherein the step of combining the weighted first antenna signal with the weighted second antenna signal further comprises adjusting a first and second adaptation step size, the first adaptation step size being determined by the adaptation strategy substantially controlled by the first algorithm and the second adaptation step size being determined by the adaptation strategy substantially controlled by the second algorithm.
