Abstract:
A method for multi-rate coding and detecting in a communication system in which data and user information are transmitted on a radio path between a transmitting end and a receiving end, the method comprising:allocating different signal waveforms to different transfer rates;selecting, at the transmitting end, a data transfer rate to be used on the radio path for transferring the user information;selecting, at the transmitting end, a signal waveform to be used on the radio path according to the selected data transfer rate;transmitting the user information with the selected transfer rate and the selected signal waveform to the receiving end, said 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; andadapting reception to the selected transfer rate.
