An apparatus for noise mitigation in a multi-carrier communication system includes a filter to receive a signal from an analog front end, a time-domain equalizer (TEQ) coupled with the filter, a fast Fourier transform (FFT) module, a frequency-domain equalizer (FEQ) coupled with the FFT module, a slicer to serve as a decision device, and a controller to calculate a power of signal at at least one of an input of the filter, an input of the TEQ, an output of the TEQ, an output of the FFT module, an output of the FEQ or an output of the slicer and compare at least one of the power of the at least one signal with a respective threshold so as to determine whether impulse noise occurs, wherein the controller is configured to disable adaptation of system parameters in at least one of the FEQ, a phase-lock loop (PLL) or a digital echo canceller (DEC) when impulse noise is detected.
