ABSTRACT:
A receiver for receiving a spread spectrum signal, comprising means for receiving a combination signal comprising a user signal spread with the user's spreading code, means for correlating the received combination signal for observing correlation between the user's spreading code and spreading codes used in the combination signal, means for regenerating the user signal by means of a user signal estimate and the user's spreading code, wherein the receiver comprises means for providing the user's spreading code synchronously to the means for correlating and the means for regenerating.
