Abstract
A communication system that can satisfactorily communicate with a mobile station by a transmitter and receiver of a simple arrangement wherein a plurality of carriers having different frequencies are transmitted simultaneously and data is transmitted on the basis of a phase difference between the carriers. Also, the carriers are multiplied with a predetermined time waveform and transmitted, so that a reception side receives data by use of a time waveform narrower than the above time waveform.
