Abstract:
     The present invention discloses B-code demodulation method, and the key points of the method include that the B(AC) signal or the generated and received analog signal has the same frequency, the same phase and different amplitude with the analog reference signal and meets b1|Di| and one low level is output or else as the digital B signal B(DC). The present invention has precise demodulation of B code to meet the requirement of high precision time sync.
