Abstract
A method and apparatus for harmonic distortion compensation in power line communications. In one embodiment, the method comprises analyzing a waveform generated by a transmitter of a power line communications transceiver (PLCT), wherein the waveform is analyzed to determine harmonic information for one or more harmonics of a carrier waveform of the PLCT; computing, based on the harmonic information, one or more harmonic compensation coefficients; and pre-distorting, based on the one or more harmonic compensation coefficients, the carrier waveform such that the one or more harmonics are reduced below a threshold.
