Patent ID: 8081934

Claim:
A power line communication (PLC) device for use in adapting an appliance to a PLC computer network, comprising: a PLC data transmitter, comprising: a forward error correction encoder receiving data to be transmitted and error correction encodes the data to produce an error corrected output; an interleaver that receives the error corrected output and interleaves the error corrected output to produce interleaved output data; a serial to parallel converter receiving the interleaved output data and producing a parallel output signal; a modulator receiving the parallel output signal and producing a modulated output therefrom; an inverse fast Fourier transformer receiving the modulated output and producing a transformed output signal at a plurality of frequencies; a user configurable notch filter, receiving the transformed output, for reducing the amplitude of a user selected range of frequencies, and producing a filtered output; a PLC interface receiving the filtered output and transmitting the filtered output over the power line; and where the user configurable notch filter is configured via a user interface, where the user interface is adapted to permit the user to select a frequency band to be attenuated by the user configurable notch filter, and where the user interface is further adapted to permit the user to select a time for deactivation of the attenuation of the selected frequency band.
