Statistical-physical modeling of electromagnetic noise

The fundamental numerical techniques used to calculate the amplitude probability distribution (APD) of nonGaussian electromagnetic noise envelopes are summarized with special emphasis placed on the interpretation of the physical meaning of the descriptive parameters. In particular, the Middleton physicostatistical models, which can be used for noise of class A as well as class B (narrow band or wide band noise) are fully studied in view that original numerical results can facilitate the interpretation of most statistical parameters. A set of significant results then shows that it is possible to predict the behaviour of a noisy environment through an analysis of the different curves obtained numerically.
