Abstract:
A method for performance improvement of a digital wireless rake receiver having a plurality of finger signals comprising the following steps:determining a corresponding conjugate of channel estimate for each finger signal of the plurality of finger signals; determining a corresponding variance for said each finger signal of the plurality of finger signals, said corresponding variance is Vl=E&boxur;|Plâˆ’E[Pl]|2&boxul; where Vl is the variance, E is the expectation operation and Pl is de-spreader output at an lth path for pilot channel; generating a plurality of weights wherein weights are generated as a function of said corresponding conjugate of channel estimate and said corresponding variance; applying said plurality of weights to the plurality of finger signals producing a plurality of weighted signals; and, combining said plurality of weighted signals producing a processed signal.
