Abstract: A method and apparatus provide for stable signal demodulation in a communication system. The method and apparatus includes including detecting an erroneous demodulation value based on backward-demodulation of received signals, using a difference between a received signal to be demodulated and a preceding signal of the received signals and correcting the error demodulation value. Alternatively, backward-demodulation is used to confirm received signals.
