Abstract
A RAKE receiver with demodulating fingers is presented having the capability to assign a specific sample stream, from among a plurality of received sample streams, to any of the demodulating fingers. The demodulating finger includes a MUX to receive the plurality of sample streams. Commands from a controller to the MUX of a demodulating finger select a specific sample stream to be demodulated by that demodulating finger. Since each demodulating finger receives all the sample streams, and any sample stream can be selected, the receiver has the flexibility of optimally varying the assignment of demodulating fingers to sample streams. A method for selecting a sample stream for demodulation, from among a plurality of sample streams, is also provided.
