- In this paper, the time-frequency distribution property of Time-Phase modulation (TPM) signal is discussed based on nonstationary signal analyzing method. And the mapping relationship between abrupt phase change and time-frequency distribution amplitude in TPM signal is further explored, whereby a TPM signal demodulation algorithm is proposed. Furthermore, this paper gives the performance analysis of the demodulation algorithm and investigates the problem of optimum decision threshold. Simulation is carried out to verify the validity of the theoretical analysis. And the results show that the demodulation algorithm proposed in this paper can offer better error performance than that of traditional correlation demodulation for TPM system.
