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.
