IEEE Transactions on Electromagnetic Compatibility · 1979 · 120 citations · 13 references

TL;DR

The paper summarizes principal non‑Gaussian noise‑model results and examines their implications for measurement and performance prediction of receivers. It reviews model statistics, parameter‑estimation methods, finite‑sample accuracy, and outlines conditions and key properties that enable optimal algorithm gains. The models enable substantial performance improvements over Gaussian‑optimized systems and provide a systematic framework for measuring, assessing, and predicting receiver performance in real‑world EMI environments.

Abstract

The chief aim of this paper is to provide a short technical summary of the principal noise-model results (11-[11], developed by the author to date, and to consider their major implications for 1) measurement, and 2) performance prediction and evaluation. The discussion is illustrated by a concise review of model statistics, methods of estimating the model parameters, including the effects on accuracy of finite data samples. A variety of signal detection problems are similarly used to illustrate the very large potential improvement possible when optimum algorithms are employed, vis-a-vis most of the currently used systems, which are conventionally optimized for Gaussian interference. Conditions for realizing such gains are also given, and the principal key properties of these new, general models are discussed. These models make possible, for the first time, a systematic treatment of real-world EMI environments, both for measurement and assessment, and for receiver performance therein.
