Abstract:
A spread spectrum communication system comprising 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 of said base stations including: accumulation means for accumulating a first reception timing difference indicating a difference between a first reception timing of a first transmission signal from a mobile station to a first base station in a first adjacent site and a second reception timing of a second transmission signal from said mobile station to a second base station in a second adjacent site; and calculation means for obtaining the second reception timing of the second transmission signal from said mobile station to the second base station by using a second reception timing difference between the first base station and the second base station acting as a handover source base station in the second adjacent site, which is accumulated in said accumulation means, when the first base station becomes a handover destination base station upon handover of said mobile station between the first and second adjacent sites.
