摘要
本文介绍一种产生同时具有给定功率谱形状和幅度概率分布随机序列的方法,由于采用时间滑动的卷积算法,使得可以连续产生模拟的噪声信号,且噪声过程任意时刻起的一段样本均具有设定的特征。文中还给出了产生连续模拟噪声过程的实例。
Abstract: A method for generating a random time sequence having both specified amplitude probability distribution and desired power spectrum features is introduced in this paper. Based on the convolution algorithm of using sliding time-window, the continuous analog noise with desired characteristics can be generated. At last, an example of simulating a noise process is given.
