DIRECT SPREAD RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a direct spread receiving device reducing the mutual interference of multi-paths due to direct spread signals having the same data simultaneously transmitted from a plurality of transmitting stations in the soft hand off or the like. SOLUTION: An interference canceller 5 corresponding to an A base station of this direct spread receiving device virtually generates the direct spread reception signal of paths other than a path PA whose power is the maximum and the direct spread reception signals of all the paths from a B base station 161 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 the path PA whose power is the maximum. An interference canceller 6 corresponding to the B base station outputs the inverse spread signal of a path PB whose power is the maximum in the same way. A synchronization judging part 7 judges the data of a user channel C by synthesizing the two inverse spread signals.
