Patent ID: 7333532

Claim:
A rake receiver for a spread-spectrum (SS) signal, the rake receiver comprising: sampling circuitry adapted to generate a stream of samples corresponding to the SS signal; a plurality of rake fingers, wherein each rake finger corresponds to a different multipath component of the SS signal and a first rake finger corresponding to a first multipath component comprises: a detection path adapted to detect symbols based on the stream of samples; and a synchronization (synch) path adapted to control timing of the sampling circuitry, wherein the synch path comprises: front-end synch circuitry adapted to apply three or more time delays, weighting, and SS correlation to the stream of samples to generate front-end output signals; and back-end synch circuitry adapted to generate one or more control signals for controlling the timing of the sampling circuitry based on the front-end output signals; and a weighting controller adapted to adaptively control the weighting applied by the front-end synch circuitry to minimize effects of one or more other multipath components associated with one or more other rake fingers of the rake receiver.
