Abstract

A cellular mobile communication system has a problem that communication quality is lowered by increase of an attenuation amount of a desired signal and increase of an interfering signal amount at a position apart from a base station and high-speed data communication becomes difficult. To solve this problem, when a mobile station M is at a location D where the radio attenuation is small, the mobile station M uses an OFDM signal to transmit data x, y and z via a traffic channel all at once so that data communication is performed at the maximum communication speed. On the other hand, when the mobile station M moves from the location D to a location E which is far from any of the base stations A, B and C, the mobile station M divides, the data x, y and z into three and, by using a diffusion OFDM signal having a high interference resistance, increases the interference resistance, and transmits data, x, y and z almost simultaneously from the three base stations A, B and C, thereby realizing equivalence of high-speed data transmission.
