Abstract: Disclosed are a signal demodulation method and apparatus, a computer storage medium and a device. The method comprises: acquiring a signal to be demodulated; performing direct current blocking and bias processing on the signal to obtain a processed signal; comparing the processed signal with a preset decision signal, and obtaining a demodulation signal according to a comparison result. Thus, direct current blocking processing on a modulation signal can avoid dynamic changes of DC components caused by average power changes of carrier signals, avoiding wrongly demodulating the modulation signal. Bias processing after the direct current blocking on the modulation signal can further realize an AC signal decision without introducing a negative pressure source. A real-time decision on the processed signal via the preset decision signal can dynamically adapt the average power of carrier signals, thereby ensuring to correctly demodulate the modulation signal and improving the accuracy of demodulation results.
