摘要：According to one embodiment taught herein, a method of determiningimpairment correlations between a plurality of delays of interest for a received CDMAsignal comprises generating kernel functions as samples of a net channel response of the

received CDMA signal taken at defined chip sampling phases for delay differencesbetween the plurality of delays of interest. In a parametric Generalized Rake (G-Rake)receiver embodiment, the delays of interest represent the delay positions of the fingersbeing used to characterized received signal. In a chip equalizer receiver embodiment, thedelays of interest represent the delay positions of the equalizer taps. The methodcontinues with determining impairment correlations based on convolving the kernelfunctions. Corresponding receiver circuits, including an impairment correlation estimationcircuit configured for parametric G-Rake operation, may be implemented in a variety ofcommunication devices and systems, such as in wireless communication network basestations and mobile stations.
