ABSTRACT:
A cellular radio system at least one transceiver which receives a signal packed into frames, a coder for channel coding the signal received by the transceiver prior to transmitting the signal as bits, and a vocoder for source coding the signal. The coder forms and adds check bits to the signal to be transmitted, the check bits being used in detecting errors causes by transmitting the signal. The coder adds the check bits in the channel coding to reduce the number of bits in the frames received by the transceiver.
