“…• Firstly, the empirical amplitude typically obeys a strongly non-Gaussian distribution [3]- [5]. More explicitly, compared to that of the Gaussian distribution having the same mean and variance values, the probability density function (PDF) of impulsive noise is more concentrated around its mean value and exhibits a longer tail.…”

“…• Secondly, the impulse duration ranges from microsecond to milliseconds. Specifically, the dominant impulses are typically shorter than 0.4 ms while a significant fraction of impulses are found to span upto 1.4 ms [5]. Bearing in mind that the duration of a DMT symbol is 20.83 µs in the G.fast standard [2], a single impulse is long enough to contaminate several consecutive DMT symbols, potentially leading to dropping an entire packet.…”

“…Specifically, impulses in DSL are typically caused both by switch-on/off of home appliances and by radio frequency interference imposed by aeronautical communications, satellite amateur communications, and FM radio broadcasting, etc. [3]- [5]. These impulses of noise can be generally classified into repetitive electrical impulse noise (REIN), single high impulse noise events (SHINE) and prolonged electrical impulse noise (PEIN) [5].…”

“…[3]- [5]. These impulses of noise can be generally classified into repetitive electrical impulse noise (REIN), single high impulse noise events (SHINE) and prolonged electrical impulse noise (PEIN) [5]. More explicitly, REIN appears periodically associated with a specific spectral envelope, while SHINE typically occurs in a transient pattern and PEIN commonly lasts for a certain period of time.…”

“…Following this, Mann et al [4] conceived a noise model for the VDSL standard, by extending the frequency band upto 30 MHz. In their recent work, Drooghaag et al [5] explored the frequency range spanning upto 212 MHz for characterizing the noise environment in the G.fast standard. In order to alleviate the influence of impulsive noise, various mitigation techniques have been proposed.…”

Digital subscriber lines (DSL) relying on twisted pairs and on home-passed fiber network, are still widely deployed in a large part of the world. However, its performance is severely restricted by the occurrence of impulsive noise. In this article, we present both the state-of-the-art and open research opportunities for impulsive noise mitigation in DSL. Its necessity is firstly discussed by briefly characterizing the impulsive noise and outlining the deleterious effects imposed on the system. Then, the state-ofthe-art is discussed by categorizing of the mitigation techniques into those at the transmitter as well as into parametric and nonparametric mitigation solutions at the receiver, followed by a detailed comparison in terms of mitigation efficiency, spectral efficiency, computational complexity and processing delay. Open research opportunities are discussed from the perspective of noise modeling for parametric mitigation, advanced mitigation design and machine-learning aided mitigation.

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 nonparametric 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. Index Terms-Power-line communications, background noise, impulsive noise, narrow-band interference, noise modeling and mitigation techniques. I. INTRODUCTION A. Power-Line Communications Power-line communications (PLC) has been considered as a means of data transmission since the late 19th century [1, Ch. 1]. Early applications include narrow-band voice and data communications over both medium-and high-voltage power lines for telemetry, telecontrol and teleprotection purposes, as the predecessors of to contemporary smart grid communications [2]-[6]. However, communications over power-lines have not received wider attention until the late 1990s [7], when both the telecommunications services and the electricity industry T. Bai, M. Elkashlan and A. Nallanathan are with the School of Electronic Engineering and Computer Science,
