Present paper deal with the analytical treatment for the forward link (base station to mobile station) erlarg capacity of the 3rd Generation CDMA based system known as WCDMA along with the different services of data rate in multipath fading channel. The erlarg capacity of the system is calculated in term of required power at the base station supports number of user in a active cell. Forward link capacity depends on the DL transmit (Tx) power at the base station in a active cell. By introducing variable orthogonality factor, transmitter antenna gain and voice activity, we analyzed the required base station power when the number of users in a active cell work simultaneously in a multirate scenario at downlink FDD mode of WCDMA. The result in this paper can be applied to overall system design of WCDMA system with voice, data and multimedia services in the future mobile communications systems.
