| Abstract(in English) | In low earth-orbital satellite communication systems,signals are affected Doppler shift whose value is large and rapidly changing. In this paper,we examine a method of carrier regeneration and the performance of a block demodulator when the signals are affected by Doppler shift.The carrier phase estimated by the block demodulator contains erroneous phase jumps caused by noise,and these phase jumps bring serious degradation in the performance of the block demodulator.We thus propose a new strategy to remove these erroneous phase jumps and compute the error rate performance of a QPSK signal with this strategy by computer simulation.As the results,it is shown that the proposed strategy can remove the erroneous phase jumps extremely and gives us good performance even though the time derivative of Doppler shift is large,where conventional block demodulators are not applicable. |
