Abstract
A receiver includes a searcher to identify pilot signals within a received signal and a pilot tracking unit to continuously track pilot signals identified by the searcher. The pilot signals tracked by the pilot tracking unit may include pilot signals associated with an affiliated base station as well as pilot signals associated with non-affiliated base stations. In at least one embodiment, the pilot tracking unit continuously tracks most or all of the pilot signals identified by the searcher.
Claims33
A receiver system comprising:
- a searcher to identify pilot signals within a received signal, said pilot signals corresponding to a plurality of remote base stations;
- and
- a pilot tracking unit to continuously track pilot signals identified by said searcher, said pilot tracking unit to track at least one pilot signal associated with an affiliated base station and, when identified by said searcher and selected for tracking, at least one pilot signal associated with a non-affiliated base station.
A method for processing a received signal within a communication device, comprising:
- identifying pilot signals within the received signal, said pilot signals being associated with a plurality of remote base stations;
- and
- continuously tracking identified pilot signals for timing and channel information, wherein continuously tracking includes continuously tracking at least one pilot signal associated with an affiliated base station and continuously tracking, when identified during identifying pilot signals and selected for tracking, at least one pilot signal associated with a non-affiliated base station.
A receiver system comprising:
- a searcher to identify pilot signals within a received signal, said pilot signals corresponding to a plurality of remote base stations;
- a pilot tracking unit to continuously track pilot signals identified by said searcher for timing and channel information, said pilot tracking unit to track at least one pilot signal associated with an affiliated base station and, when identified by the searcher and selected for tracking, at least one pilot signal associated with a non-affiliated base station;
- at least one rake receiver to demodulate data within the received signal that is associated with a corresponding user, said at least one rake receiver having a plurality of rake fingers;
- and
- a controller to manage the operation of said searcher, said pilot tracking unit, and said rake receiver, wherein said controller includes a selection module to select individual pilot signals identified by the searcher to be continuously tracked by the pilot tracking unit.
