Abstract：Based on the function of the synchronization status monitor of Q-1900, a new method for correct-ing output data status of all digital coherent QPSK demodulation is presented. The correcting capability ofthe quadriphase differential coding and decoding is also analysed in theory. The experiment results showthat this method is of the complete performance which the quadriphase differential coding and decoding cannot achieve.
