• For the channel estimation in the pilot channel aided CDMA systems which can support a multi-code scheme, we consider a linear prediction using both pilot and traffic channels After deriving a new form of the optimal Wiener filter which requires less computational load, for its practical implementation, we propose the decision-directed adaptive linear prediction filter (DD-ALPF) To prevent from falling into the false lock, the proposed DD-ALPF uses the conventional channel estimate obtained only from pilot channel as a baseline for checking the reliability of the filter output It will be shown through computer simulation that the proposed method can improve the receiver performance and performs better in the fast fading environments, compared with the existing ones
