The Recognition of Hybrid Modulation Signal Combined with PRBC and LFM

摘要：

　　The recognition of hybrid modulation signal combined with pseudo-random binary phase code (PRBC) and linear frequency modulation (LFM) is investigated.Firstly,with the help of binary tree,we present a recognition methodology for signals including PRBC-LFM hybrid modulation signal,BPSK signal and LFM signal based on phase unwrap and instantaneous frequency(IF).Whats more,the decision of recognition thresholds based on Neyman-Pearson (N-P) criterion is discussed and analyzed in detail.In the end,the simulations about recognition of PRBC-LFM signal are implemented,and results indicate our methodology possesses fine recognition performance in proper SNR levels.
