A RAKE receiver for receiving a spread spectrum signal, the RAKE receiver comprising at least two antennas for receiving a spread spectrum signal containing several user signals, at least one delay unit for delaying the spread spectrum signal received in at least one antenna to prevent the spread spectrum signals received from the different antennas from being cancelled, an adder for combining the spread spectrum signal received in at least two antennas to form a combination signal, and a matched filter for generating a user signal combination impulse response by means of the combination signal.
