Patent ID: 8064556

Claim:
A method of equalization in a spread spectrum wireless communication system comprising: estimating a channel impulse response; estimating channel variance by computing a covariance sum comprising values for samples received at different times; and selecting filter coefficients for an equalizer based on the estimated channel impulse response and the estimated channel variance; wherein the equalizer is a fractionally spaced equalizer including one or more equalization filters having filter coefficients spaced a fraction of a chip apart, and wherein said selecting filter coefficients is based on the estimated channel impulse response and the estimated channel variance for a plurality of fractionally spaced chip samples; the method further comprising: combining the output of one equalization filter in a first manner for no diversity; combining the output of two or more equalization filters in a second manner for transmit diversity; and combining the output of two or more equalization filters in a third manner for receive diversity.
