Abstract

A non liner device (NLD) between powerline communication (PLC) devices can introduce significant distortion into the channel being utilized by the PLC devices. This distortion can create errors and corrupt data transmitted by the PLC devices. When trying to mitigate the effects of the distortion introduced by NLDs PLC devices conform their mitigating actions to effectively satisfy a limit(s) set by a regulation and/or a standard. A PLC device implemented in accordance with this disclosure can mitigate the distortion effects with deference to regulatory/standard limits without knowledge of what types of NLDs and how many NLDs are coupled to the power line. A PLC device can use different techniques to infer the presence of an NLD in a PLC network. A PLC device can infer the presence of the NLD using a passive technique or one or more active techniques.
