摘要
提出一种产生伪随机PPM信号的方法 ,并利用产生的伪随机PPM信号调制伪随机码获取PPM伪随机码。推导了PPM伪随机码的自相关函数和功率谱 ,并结合图形分析了它们的特点。
A method of generating a pseudo random PPM signal which is used to modulate the pseudo random code to get PPM pseudo random code is put forward. The autocorrelation function and power spectrum of the PPM pseudo random code are derived, and their character istics are analyzed on the basis of their pictures. At last, the application of the PPM pseudo random code to pseudo random code phase modulation and pseudo random pulse position modulation combined fuze is introduced.
