PROBLEM TO BE SOLVED: To provide a direct spread receiver reducing the interference of mutual multi-paths due to direct spread signals simultaneously transmitted from a plurality of transmitting stations in the soft hand off or the like. SOLUTION: In this direct spread receiver, a base station having a path Px whose power is the maximum is selected as an X base station according to the impulse responses of reception signals from A and B base stations. An interference canceller 5 virtually generates the direct spread reception signals of paths other than the path Px whose power is the maximum from the X base station and the direct spread reception signals of all the paths from the base station other than the X base station as an interference replica based on initial reception data, and removes the virtually generated signals from the received direct spread signal, and outputs the inverse spread signal of a user channel C of the path Px whose power is the maximum. |
