<p>The invention relates to a data transfer method and a cellular radio system which comprises at least one transceiver (100, 200) which receives a signal packed into frames, means (202) for channel coding the signal received by the transceiver prior to transmitting the signal which consists of bits, and a vocoder (300) for source coding the signal. The means (202) form and add check bits to the signal to be transmitted, the check bits being used in detecting errors caused by transmitting the signal. The means (202) add the check bits in the channel coding to reduce the number of bits in the frames received by the transceiver.</p> |
