Patent ID: 8254325

Claim:
A method of estimating a propagation channel response corresponding to a received signal in a wireless communication receiver the method comprising: selecting a plurality of receiver processing delays for sampling the received signal so that the plurality of receiver processing delays span two closely spaced channel response delays, a presence of closely spaced channel response delays in the propagation channel response indicated by a variance of error metrics exceeding a pre-determined threshold; calculating an average channel coefficient magnitude over at least a first number of time slots of the received signal, for each of the receiver processing delays; estimating delay timing for each of the two channel response delays, based on the average channel coefficient magnitudes and a multi-delay superposition model for the channel response for the each of the two closely spaced channel response delays; and calculating complex channel gains for each of the two channel response delays, based on the estimated delay timings and channel response measurements taken over a second number of time slots that Is less than the first number of time slots.
