According to the system of the present invention, in a base station, a radio transmission characteristic of a forward link is estimated by a parameter estimating section 18b based on a receiving state of a radio signal arrived from a mobile station through a reverse link. Then, RAKE control data to be set to a RAKE receiver of the mobile station is generated based on the result of the estimation, and RAKE control data is notified to the mobile station. On the other hand, in the mobile station, RAKE control data is extracted by a RAKE control data extracting section. Then, a tap coefficient is initialized to be set to a transversal filter of the RAKE receiver based on RAKE control data.

[ What is claimed is:] [1.] A spread spectrum radio communication system including a function of transmitting an original transmission signal between a base station and a mobile station, and a function of synthesizing a plurality of the same transmission signals received to have a time difference by a signal receiving/reproducing circuit including delay means and synthesizing means so as to reproduce said original transmission signal to said mobile station,said base station comprising:weighting data generating means for generating weighting data to be provided to said synthesizing means of said signal receiving/reproducing circuit in accordance with a characteristic of a radio transmission path between said base station and said mobile station; andweighting data transmitting means for transmitting weighting data obtained by said weighting data generating means, andsaid mobile station comprising:weighting data receiving means for receiving weighting data notified from said base station; andweighting data setting means for setting weighting data received by said weighting data receiving means in said synthesizing means, whereby said synthesizing means synthesizes the received same transmission signals in accordance with said weighting data.
