Abstract
A system for processing radio frequency (RF) signals includes a searcher and a Cluster Path Processor (CPP). The searcher detects a maximum signal energy level and position of at least one of a plurality of individual distinct path signals in a signal cluster, wherein at least a portion of the plurality of individual distinct path signals is received within a duration of a corresponding delay spread. The CPP includes a group finger array having a plurality of group fingers and determines a coarse sampling position of the group finger array based upon the position of the at least one of a plurality of individual distinct path signals in the signal cluster. The CPP determines a fine sampling position based upon determines a composite channel energy estimate for the plurality of individual distinct path signals. Using this fine sampling position, the CPP receives at least a portion of the plurality of individual distinct path signals by the group finger array.
