ABSTRACT:
A receiver for receiving a spread spectrum signal, including mechanisms for receiving a combination signal including a user signal spread with the user's spreading code, mechanisms for correlating the received combination signal for observing correlation between the user's spreading code and spreading codes used in the combination signal, mechanisms for regenerating the user signal using a user signal estimate and the user's spreading code, wherein the receiver includes mechanisms for providing the user's spreading code synchronously to the mechanisms for correlating and the mechanisms for regenerating.
