Abstract:
The present invention concerns a method and device for cancelling interference between a signal carried by a carrier current line of a system distributing digital services at the home of a subscriber and a signal carried by a telephone line of said system that is situated close to the carrier current line. The method is characterized in that it consists of obtaining the signal carried by the carrier current line, filtering it in order to obtain an estimate of the signal that disturbs the signal carried by the telephone line and subtracting this estimate from the signal carried by the telephone line.
