Abstract

A blind sub-carrier recognition algorithm of TT&C communication is proposed based on JTFA(Joint Time-Frequency Analysis)and Fast-ICA Algorithm. In this method, we use time-frequency analysis technology to extract the features of the satellite signals, and Fast-ICA to enhance SNR ( Signal Noise Ratio) effectively. As one of the best tools to analyze the non-stationary signals, it shows information in the joint time-frequency domain and makes us know about the change of frequency along with the time clearly. Before the time-frequency analysis of the satellite signal, the premise is to remove noise. This paper presents a method of Satellite TT&C signal recognition. The analysis results show that the algorithm has good effect and good convergence in the satellite TT&C signal extraction. The characteristic of this algorithm is that we need not any prior information of signals to recognize any TT&C signals of satellite.
