A multi-carrier RAKE receiver is described herein. The multi-carrier RAKE receiver distributes RAKE fingers between a plurality of received carriers based on a comparison between the signal-to-interference ratios (SIRs) determined for each carrier. In one embodiment, the RAKE fingers are distributed evenly between the carriers when a comparison between the largest and smallest SIR is less than or equal to a threshold. In another embodiment, the RAKE fingers are distributed to favor the carrier(s) with the strongest SIR(s) when the comparison between the largest and smallest SIR exceeds the threshold. By distributing the RAKE fingers to favor the carriers with the strongest SIRs, the embodiments of the present invention enable the system designers to limit the total number of available RAKE fingers without sacrificing performance.
