Method and apparatus for stable signal demodulation in communication system

摘要

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.

1. A signal demodulation method, comprising:
demodulating received signals using a difference between a received signal to be demodulated and a preceding signal of the received signal; detecting an erroneous demodulation value based on backward-demodulation of the received signals; and correcting the erroneous demodulation value, wherein the demodulating comprises determining a demodulation value of the received signal to be demodulated as a first demodulation value in response to a differential value being less than a first threshold, the differential value corresponding to a difference between an intensity of the received signal to be demodulated and an intensity of the preceding signal, and determining the demodulation value of the received signal to be demodulated as a second demodulation value in response to the differential value being greater than a second threshold.
