摘　　要：隐蔽通信对信号的隐蔽性能提出了很高的要求,为提高信号传输的隐蔽性能,适应现代隐蔽通信的发展需求,提出了一种噪声调制技术。噪声调制不同于传统的调制技术,利用噪声波形代替正弦波形,信号以真正的噪声波形进行传输,并具备一定的带宽优势;设计了一种直接采用噪声调制的通信系统方案,并分别与BPSK调制技术和直接序列扩频技术在抗噪声性能与隐蔽性能上进行了仿真对比,验证了噪声通信的可行性。The covert communication has high requirements on covert performance of signal.In order to improve the covert performance of signal transmission and meet the development of modern covert communication,this paper puts forward a noise communication technology.Different from the traditional modulation technology,the noise modulation technology replaces noise waveform with sine waveform and transmits the signals by using real noise waveform,which has some advantage on bandwidth.A communication system solution using noise modulation is designed,which is compared with BPSK and DSSS,on anti-noise performance and covert performance. The simulation and comparison results prove the feasibility of noise communication.
