Abstract: PROBLEM TO BE SOLVED: To provide techniques for assigning multipaths to finger processors to achieve desired data performance and low power consumption.SOLUTION: A search is initially performed to obtain a set of multipaths for a transmission from at least one base station. At least one multipath (e.g., the minimum number of multipaths) having a combined performance metric (e.g., a combined SNR) exceeding a threshold is identified. The at least one multipath is assigned to, and processed by, at least one finger processor to recover the transmission from the base station(s).
