    摘要： A power line communication modem includes a receiver that receives a noise signal over a power line channel. The signal is OFDM-modulated on a set of sub-carriers, the sub-carriers being separated by a frequency separation. The power line communication modem also includes a processor that identifies a presence of a radio service within one or more fine frequency bands with a first resolution bandwidth by analyzing a plurality of fine frequency bands. The first resolution bandwidth is smaller than the frequency separation. The power line communication modem additionally includes a transmitter that excludes a signal in at least one of the plurality of fine frequency bands, in which the presence of the radio service has been identified, before transmitting the excluded signal.

    摘要： A method for detecting an ingress of a short wave radio signal in a power line communication system which determines a strength of a common mode signal at a frequency of the power line communication system during a time period when no communication in the power line communication system at this frequency takes place and an ingress is detected if the strength of the common mode signal is above a determined threshold. A corresponding power line communication modem can implement such a method.
