Abstract:

Base on existing Extended Binary Phase Shift Keying (EBPSK) signal model, the time- frequency characteristic of EBPSK was analyzed using nonstationary signal analysis method. A model of the relationship between phase discontinuity and the amplitude of time-frequency distribution of EBPSK signal was proposed. Using this model, a time-frequency distribution based EBPSK demodulation algorithm was developed, and the structure of the demodulator was given. The performance of the demodulation algorithm was analyzed, and the selection method of the judging threshold for the demodulator was explored. Simulation and theoretical analysis results demonstrated that the EBPSK demodulation algorithm not only simplifies the structure of the EBPSK demodulator and obtains good error-correction performance but also provides a new feasible scheme for nonstationary signal processing in communication.

Key words: communication, nonstationary signals analysis, time-frequency distribution, discontinuity of phase bandwidth, extended binary phase shift keying(EBPSK)
