1. clock regenerating signal device is characterized in that comprising:

  • Use the clock signal of the signal defined frequency of the subcarrier band that obtains based on main carrier frequency demodulating ofdm modulation signal to carry out digitized processing, and with the demodulator circuit of digitized restituted signal output;

    Make above-mentioned restituted signal delay that obtains by described demodulator circuit and the delay circuit that delayed delay restituted signal is exported;

    The phase place variation output circuit of the phase place variation output between the pilot signal that comprises during the symbol with described ofdm modulation signal based on described restituted signal and these two signals of described delay restituted signal;

    The control circuit of the frequency of described clock signal being controlled based on the output of described phase place variation output circuit.
