Abstract

In a communication system in which data and user information are transmitted on a radio path between a transmitting end and a receiving end, multirate coding and detection are carried out by: allocating different signal waveforms to different transfer rates, selecting, at the transmitting end, the data transfer rate to be used on the radio path for transferring user information, selecting, at the transmitting end, the signal waveform to be used on the radio path according to the selected transfer rate, transmitting the user information with the selected transfer rate and the selected signal waveform to the receiving end, the signal waveform indicating the selected data transfer rate, detecting, at the receiving end, the signal waveform used on the radio path, selecting, at the receiving end, a transfer rate corresponding with the detected signal waveform, and adapting reception to the selected transfer rate.
