摘要
对仿真中用到的各种随机信号的数学模型进行了讨论。定量分析了有限带宽白噪声模块BLWN,给出了设定该模块参数的关系式。对有色噪声的仿真进行了定量的分析和验证。分析了指数相关随机过程的数学模型,指出仿真时可用均匀分布来代替泊松分布,并给出了相应的M函数文件。文中还讨论了仿真中用BLWN模块来近似给出指数相关随机过程的方法。
The mathematical models of stochastic signals used in simulation are discussed. Detailed quantified analysis is given for the Band-Limited White Noise module and its parameters. The generation of colored noises in simulation and its verification are also discussed. The mathematical model of the exponential correlation process is analyzed. It is pointed out that the equal distribution can be used in simulation instead of the Poisson distribution to produce an exponential correlation process, and the related M-function is given. An approximate method of generation the exponential correlation process from BLWN module is also discussed.
