I. Introduction
Asynchronous impulsive noise is ubiquitous in Power Line Communication (PLC), which is a strong candidate for the Smart Grid as it eliminates the need for new networking infrastructure. However, the power-line channel is not useful for communication without suitable network design, and the PLC has very limitedly use due to noise. Impulsive noise, in particular, is one of the impairments of PLC systems therefore its modeling and mitigation have attracted a lot of attention over the past decade [1]–[3].
