ABSTRACT:
In a CDMA communications network a mobile station includes wanted signal processing circuitry (12) for processing an input signal (PRX), representing a CDMA transmission signal received at the mobile station from a base station of the network, to derive therefrom a wanted signal embodying a preselected spreading code. The mobile station also includes code information receiving circuitry (52) which receives from the base station code information (CIi1–CIim) identifying a further spreading code assigned by the network to an interfering signal of another network user. Interfering signal processing circuitry (14) employs the further spreading code identified by the received code information to reduce the interference effect of that interfering signal on the derived wanted signal.
