Patent ID: 7848389

Claim:
A method of estimating one or more scaling parameters used to scale modeled impairment correlations in a parametric Generalized RAKE (G-RAKE) receiver comprising: estimating the scaling parameters on a per transmission interval basis such that the scaling parameters estimated in one transmission interval of a received communication signal are not influenced by the scaling parameters estimated in another transmission interval of the received communication signal; wherein each transmission interval comprises one or more transmission slots, and wherein estimating the scaling parameters on a per transmission interval basis comprises: estimating the scaling parameters based on measured impairment correlations obtained over more than one transmission slot of the transmission interval; expressing the measured impairment correlations as a function of modeled interference correlations scaled by a first scaling parameter and modeled noise correlations scaled by a second scaling parameter; bounding the second scaling parameter according to a defined limit or range; and solving the function for the first and second scaling parameters.
