We propose a chaos - based generation of the random ppm - ps signals , design and implement a generator of the ppm - ps signals . we introduce an if sampling technique and simulate the performances of digital demodulation techniques of using hilbert filters , sine filters , bessel filters and poly - phase filters . the poly - phase filtering method can achieve the higher mirror - frequency rejection ratio by using the low order filters
介绍了中频采样技术，并对希尔伯特滤波法、辛格内插函数修正、贝赛尔函数插值法及多相滤波法等数字解调算法进行了计算机仿真和性能比较，指出多相滤波法能以较低的阶数实现较高的镜频抑制比。
