A PSK Signal Decoding Method Based on Kay's Instantaneous Frequency Measurement
Bin Zeng · Telecommunication Engineering · 2008
The modulation mode and parameters of radar signal are required to determine in electronic reconnaissance.The LFM,FSK and PSK signals can be detected by Kay's instantaneous frequency measurement and clustering method.For phase code signal,the rules of phase-shifting from signal are picked-up by using coherent integration of single pulse,and the method of recovering phase code sequence is proposed.The speed of new method is prior to the Short-Time Fourier Transform(STFT) method when the SNR is high.Finally,the computer simulation shows that this method has better precision and processing result.
