Abstract

See full text

A spread spectrum communication system includes at least one mobile station and a plurality of base stations for communicating with mobile stations in sites thereof by a spread spectrum scheme. Each base station includes an accumulation section and calculation section. The accumulation section accumulates a reception timing difference indicating the difference in reception timing between a transmission signal from a mobile station in a base station in an adjacent site and a transmission signal from the mobile station in a self-station. The calculation section obtains the reception timing of the transmission signal from the mobile station in the self-station by using the reception timing difference between the self-station and a handover source base station in an adjacent site, which is accumulated in the accumulation section, when the self-station become a handover destination base station upon handover of the mobile station between adjacent sites.
