Abstract
A CDMA receiver includes a plurality of RAKE branches for despreading the received CDMA signals over a corresponding plurality of paths and a single tracking device that is shared among the plurality of the RAKE branches for tracking the delays of the received CDMA signal over a corresponding path. Similarly, a method for tracking a CDMA signal correlates the received signal with local PN codes using a plurality of RAKE branches and tracks the received signal using a single tracking device that is shared among the plurality of the RAKE branches.
