PURPOSE: A transmission rate detecting method for a CDMA terminal is provided to get the transmission rate quickly during a demodulation action of the CDMA terminal. CONSTITUTION: If a data frame is sent to a de-interleaver from a modem, the signal of the received data frame is decoded and encoded to the transmission rate of n. The encoded signal is compared with the received signal and it is inspected whether the error is larger than a critical value or not. If smaller, then the transmission rate is transmitted to the vocoder and whether the transmission is completed or is not tested. If not completed, it is returned to the start. If the error is larger than the critical value, then the above n is set to some transmission rate except for the used transmission rate to decode and encode the current frame, and it is returned to the start again.
