Abstract: PURPOSE: A method for deciding a bit rate of a received data frame in a decoder of a mobile communication base station system is provided to determine a bit rate only by the CRC(Cyclic Redundancy Check) after granting priority to the bit rates of a frame and executing Viterbi decoding using the characteristics of a received symbol frame, before executing Viterbi decoding. CONSTITUTION: A decoder receives a soft-decided variable bit rate data frame(S101). After executing Viterbi decoding for the received variable bit rate data frame(S102), the decoder executes the CRC for the Viterbi decoded data(S103). The decoder judges whether a bit error has been generated during the execution of the CRC(S104). In case that a bit error hasn't been generated, the decoder decides an assumed bit rate as the final bit rate(S105). If a bit error has been generated during the execution of the CRC, the decoder determines priority for the bit rates of the received data frame using symbol repetitive frequency(S106). Then the decoder assumes the bit rate of the highest priority as the bit rate of the received frame(S107).
