本文概述了脉冲噪声及其模型，并指出了一些重要的和有趣的事实，脉冲噪声的研究，有时被忽视或没有很好地理解。我们讨论了不同的脉冲噪声模型在文献中，专注于它们的相似性和差异时，应用在通信系统中。所讨论的脉冲噪声模型是无记忆的（Middleton Class A，Bernoulli-Gaussian和Symmetric alpha-stable），以及有记忆的（Markov-Middleton和Markov-Gaussian）。然后，我们进一步给出性能比较的误码率的脉冲噪声模型的一些变种。我们还比较了脉冲噪声下单载波（SC）和多载波（MC）通信系统的误比特率性能。可以看出，在脉冲噪声下，MC并不总是优于SC。最后，讨论了已知的脉冲噪声抑制方案（使用阈值的限幅/置零、基于迭代的编码方法和差错控制编码方法）。
This article gives an overview of impulse noise and its models, and points out some important and interesting facts about the study of impulse noise which are sometimes overlooked or not well understood. We discuss the different impulse noise models in the literature, focusing on their similarities and differences when applied in communications systems. The impulse noise models discussed are memoryless (Middleton Class A, Bernoulli-Gaussian and Symmetric alpha-stable), and with memory (Markov-Middleton and Markov-Gaussian). We then go further to give performance comparisons in terms of bit error rates for some of the variants of impulse noise models. We also compare the bit error rate performance of single-carrier (SC) and multi-carrier (MC) communications systems operating under impulse noise. It can be seen that MC is not always better than SC under impulse noise. Lastly, the known impulse noise mitigation schemes (clipping/nulling using thresholds, iterative based and error control coding methods) are discussed.
