This paper deals with a new method for the design and implementation of a gaussian pseudorandom generator with a specific power spectral density or autocorrelation function. The method is based on the central limit theorem. The mathematical analysis of the generator, which consists of a digital ...
In this example, we calculate the autocorrelation of random Gaussian noise in Matlab. We know that autocorrelation means matching signals with the delayed version itself. Now for random Gaussian noise, only when shift= 0 is there some autocorrelation value, and for all other cases, the autocorrela...
This compound backscattered field is then imaged by a SAR, resulting in a non-Gaussian speckle pattern which appears as the pronounced azimuth streaks. A general and simple expression is derived for the autocorrelation function (ACF) of the speckle intensity in terms of the statistical properties ...

and this is not consistent with the theoretical analysis.The origin of such influence is studied in this paper,and the analytic expressions of means and variances of those undesired items(which are produced by stationary noise),as well as the simplified forms for Gaussian white noise are derived...
