METHOD AND APPARATUS FOR SHARED PARAMETER ESTIMATION IN A GENERALIZED RAKE RECEIVER

摘要

The signal impairment correlations for multiple signals in a received multipath are constructed by fitting parametric models associated with each high-data-rate signal in the multipath against measured impairment correlations. The estimated models fitting parameters are applied to form impairment correlation estimates for all signals. The models comprises a separate impairment covariance matrix scaled by a model fitting parameter for each high-data-rate signal and a noise covariance matrix scaled by a noise element model fitting parameter. The model fitting parameters may be estimated by a least-squares formulation and applied to form impairment correlation estimates for all signals of interest. The resulting impairment correlation estimates may be provided to G-RAKE receivers or joint scaling demodulators to demodulate the signals while suppressing interference from the high-data-rate signals.
