| 摘 要： | 在所有离散系统的模拟中,提供合适的概率密度函数的伪随机信号发生器是必不可少的.在某些情况下,还要求产生的伪随机信号不仅服从某一非高斯概率密度函数,而且具有某一指定的功率谱密度函数.针对这种情况,本文分析和讨论了一种伪随机信号发生器,利用它可以产生具有指定概率密度函数和功率谱密度函数的非高斯平稳随机信号,并给出了几组采用这种方法模拟的结果.

| Abstract: | A generator of pseudo—random signals with desired probability density function is indispensable to simulation of discrete systems. Moreover, it is necessary to produce a pseudo—random signal with not only a selected non—Gaussian distribution function but also a specified power spectral density function under certain circumstances. This paper analyzes a pseudo—random signal generator which can be used to generate stationary random non—Gaussian signal having a specified probability distribution function and power spectral density function. Some simulated results are also presented. |
