método para detectar um ingresso de um sinal de rádio de onda curta em um sistema de comunicação de linha de energia, e, modem de comunicação de linha de energia.

摘要

A method for detecting an ingress of a short wave radio signal in a power line communication system is described which comprises determining 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 (400, 500) is provided as well.
