PROBLEM TO BE SOLVED: To solve the problem that when a plurality of base stations are arranged, and communication of the same data is performed between the base stations and a mobile station by using multicarrier modulation method, at the same time and with the same frequency, standing wave interference is generated, an electric field level of carrier is decreased, and a bit error rate is increased, when the mobile station is brought to an area where received power of radio wave from each of the base stations becomes almost equal. SOLUTION: On the base station side, it makes possible to set phase difference between subcarriers f1 to fN. In the mobile station, many subcarriers which increase power with each other exist in the case of reception, and few subcarriers which cancel power with each other exist in the case of reception. The situation that all the subcarriers cancel each other can be avoided, and the state that correction is enabled by error correction can be formed. COPYRIGHT: (C)2003,JPO
