基于电力基础设施的普及，电力线通信（PLC）已成功应用于各种应用场景，包括智能电网和家庭宽带通信系统以及工业和家庭自动化。然而，电力线信道表现出有害特性，其中之一是其恶劣的噪声环境。本文旨在提供一个审查的噪声建模和减轻技术在PLC。具体而言，在过去的50年里，代表性的噪声模型的全面审查，包括基于测量活动的经验模型和简化的数学模型。在此之后，我们提供了一个广泛的调查套件的噪声缓解方案，将它们归类为缓解在发射机以及参数和非参数技术在接收器。此外，由于PLC中的信道估计的准确性受到噪声的影响，我们回顾了联合噪声抑制和信道估计解决方案的文献。最后，一些方向概述了未来的研究在PLC的噪声建模和缓解。
Building on the ubiquity of electric power infrastructure, power line communications (PLC) has been successfully used in diverse application scenarios, including the smart grid and in-home broadband communications systems as well as industrial and home automation. However, the power line channel exhibits deleterious properties, one of which is its hostile noise environment. This article aims for providing a review of noise modeling and mitigation techniques in PLC. Specifically, a comprehensive review of representative noise models developed over the past fifty years is presented, including both the empirical models based on measurement campaigns and simplified mathematical models. Following this, we provide an extensive survey of the suite of noise mitigation schemes, categorizing them into mitigation at the transmitter as well as parametric and non-parametric techniques employed at the receiver. Furthermore, since the accuracy of channel estimation in PLC is affected by noise, we review the literature of joint noise mitigation and channel estimation solutions. Finally, a number of directions are outlined for future research on both noise modeling and mitigation in PLC.
