Method and system for single antenna receiver system for WCDMA

摘要

A receiver receives multipath signals in a W-CDMA system. Channel estimates and timing reference signals are generated utilizing the received multipath signals. Timing correction signals indicating a location of the received multipath signals may be generated and the received multipath signals may be combined based on the computed channel estimates and/or the generated timing reference signals. The multipath signals may be combined as a signal cluster. Circuitry may be provided that computes channel estimates based on at least one of a plurality of received multipath signals, and generates timing reference signals indicating a location of at least one of the plurality of received multipath signals. Circuitry may also be provided that combines at least a portion of the plurality of received multipath signals based on at least a portion of the computed channel estimates and/or the generated timing reference signals.

1. A method for processing radio frequency (RF) signals, the method comprising:
computing channel estimates based on a plurality of chip-level data items received via a plurality of received multipath signals; generating timing reference signals indicating a location of at least one of said plurality of received multipath signals; maximum-ratio combining at least a portion of said plurality of received chip-level data items as a signal cluster to form a combined plurality of chip-level data items based on at least one of said computed channel estimates and said generated timing reference signals, wherein the maximum-ratio combining includes assigning a rake receiver finger to the signal cluster; and extracting transmitted information from said combined plurality of chip-level data items.
