A receiver arranged to receive a plurality of spread spectrum signals including a first spread spectrum signal from which interference caused by one or more others of said plurality of signals is to be removed, wherein at least one of said other spread spectrum signals has a spreading factor which is unknown to said receiver. The receiver comprises means for estimating a spreading factor of said at least one other spread spectrum signal having an unknown spreading factor, said estimating means selecting the spreading factor to be smallest possible spreading factor, means for despreading said at least one other spread spectrum signal using said estimated spreading factor, and means for estimating interference in the first spread spectrum signal caused by said at least one other spread spectrum signal. |
