<p>The invention relates to a method and equipment for multirate coding and detection in a multiple access mobile communication system. A transmitter selects (34) a data transfer rate, and codes (38, 39) the transfer rate information to a transmitted signal by using a signal waveform which is allocated to the transfer rate. At the receiving end, the signal waveform of the received signal is detected, and the transfer rate in the reception is selected according to the detected signal waveform. For example, in a mobile communication system employing frequency hopping (FH) or time hopping (TH), the hopping pattern is selected in the transmitter according to the transfer rate. In a code division multiple access (CDMA) system, a spreading code is selected according to the transfer rate.</p> |
