The Study on Parameters Extraction of Pseudo Code Phase Modulation-Carry Frequency Modulation Combined Fuse Signal Based on the Adaptive Window Length WD Analysis
The theory and its implementation on the adaptive window length in the analysis of time frequency are presented in this paper. This method is used to analysis the in-pulse characteristics of pseudo-code fuse signals such as Pseudo-Code Phase Modulation (PCPM), pseudo-code phase modulation combined by Sinusoid Frequency Modulation (SFM) and pseudo-code phase modulation combined by Linear Frequency Modulation (LFM). The simulation result shows that both the characteristic of carry frequency modulation and phase changed position caused by the pseudo-code can be extracted effectively in SNR=10dB.
