METHOD FOR DETECTING AN INGRESS OF A SHORT-WAVE RADIO SIGNAL IN A POWER LINE COMMUNICATION SYSTEM AND POWER LINE COMMUNICATION MODEM

摘要

Determining the strength of the common mode signal at one frequency of the power line communication system during a period of time in which no communication to the corresponding frequency occurs in the power line communication system when the strength of the common mode signal exceeds a predetermined threshold; A method of detecting the impression of a short wavelength radio signal in a power line communication system is provided. A corresponding power line communication modem 400, 500 is also provided.
