The dispersed-carrier-wave format is proposed for the execution of simultaneous multistation transmission for mobile communications. Signals are transmitted by modulating the carrier wave, which is frequency-modulated by sinusoidal waves. The diversity effects of this format were calculated, and the results were confirmed for the case of simultaneous two-station transmission. In cellular zone systems, in the case when the transmission distance of the radio waves is sufficiently large compared with the radius of the zone, there would be areas where several radio zones overlap. Therefore, for the theoretical calculations, the maximum number of simultaneous transmission bases was considered to be up to six stations. Also, numerical calculations of the transmission diversity effects have been made in the case of simultaneous multiple-station transmissions for a base station network with configurations of regular hexagonal meshes.
