摘　　要：随着信息通信技术的快速发展,通信对抗技术也迎来了飞速发展的时期,通信信号调制类型的识别越来越受到重视,而由于小波具备较好的时-频局部化效果,导致基于小波理论的信号识别应用越发广泛。从二进制相移键控(BPSK)调制的特性和小波的时频特性展开,选取了Daubechies小波进行调制,确定待评估信号与原信号的距离Dv为特征值,采用System View系统进行仿真实验,并得出了一定的结论。With the fast development of information communication technology,the communication countermeasure technology has come to a full-speed developing period.The identification of communication signal modulation type has been paid for more and more attention.The signal identification based on wavelet theory has been applied widely because of its better localization effect in time-frequency domain.This paper starts with the modulation characteristic of binary phase shift keying(BPSK)and time-frequency characteristic of wavelet,and chooses the Daubechies wavelet to make modulation,confirms the distance D_v between the signal assessed and original signal as characteristic value,adopts the System View to perform simulation experiment,and fetches definite conclusion.
