<p>A method for transmitting a signal over a power line channel is provided, wherein the signal is OFDM-modulated on a set of sub-carriers, said sub-carriers being separated by a frequency separation, said method comprising receiving a noise signal via the power line channel, determining respective signal values of said received noise signal within a plurality of fine frequency bands with a first resolution bandwidth, wherein said first resolution bandwidth is smaller than said frequency separation, determining a disturbed fine frequency band of said plurality of fine frequency bands based on the respective signal values and notching the signal in said disturbed fine frequency band before transmitting said signal. A corresponding power line communication modem is provided as well.</p> |
