Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04L 1/00
H04B 1/69
H04B 7/216

US Classification:

375348, 375130, 375148, 370342

Abstract:

A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.
