| 摘 要： | 本文给出了满足给定数字特征和谱的随机序列的产生方法，即用无记忆非线性变换实现非正态随机信号的模拟．该法与Ｇｕｊａｒ法相比较，放宽了变量概率分布的限制，只要求变量矩的存在。同时考虑无记忆非线性变换对谱的影响，用异于Ｌｉｕ的方法在频域上求解输入正态分布随机序列的谱．

| Abstract: | In this peper,a method of generation of random signals with given moments of variables and the spectrum is proposed,that is,the simulation of non-Gaussian random signals is realized by using zero-memory nonlinearity transformation. A comparison of this method with that of Gujar's shows that this method relaxes the restriction of the probability distribution of variables and only nedds the moments of variables. Meanwhile,considering the effect of zero-memory nonlinearity.transformation on the spectrum,this method of solving the spectrum of random sequence of normal process in the field of frequency as input is different from Liu's. |
