Abstract
In a mobile communication system in which signals are temporally compressed into time slots of a frame structure, a composite signal such as a telephone signal or data signal is hybrid-modulated using the same radio carrier wave, whereby diversity transmission/reception are available. The telephone signal is frequency-modulated using a single time slot of a single radio communication channel which has been allocated between a mobile transceiver and a radio base station. The frequency-modulated signal is again amplitude-modulated by the same telephone signal so that diversity transmission/reception is available.
