PCM DATA SYNCHRONIZATION ACQUISITION DEVICE AND METHOD IN WIRELESS LOCAL LOOP

摘要

PURPOSE: A PCM(Pulse Mode Modulation) data synchronization acquisition device and method in wireless local loop are provided to make synchronization of the demodulated data through a demodulator accord constantly in order to transmit it to PCM highway so as to prevent an abnormal PCM data decode caused by the discord of synchronization from removing. CONSTITUTION: The PCM(Pulse Mode Modulation) data synchronization acquisition device includes following units. A decoder(215) performs Viterbi decoding of the receiving signal with a predetermined unit period and generates an indication signal representing a unit period when the decoding is finished. A shift register(219) inputs the decoded data according to predetermined control. A control unit(213) controls that the decoded data is inputted to a shift register only when the setting bit of indication signal has the setting value and thereafter it is transmitted on PCM highway.
