METHOD FOR TRANSMITTING DATA IN DIFFERENTIAL MODE ON A TWO-WIRED LINK USING A COMMON ATTENUATION MODE, CORRESPONDING CONNECTION DEVICE AND COMPUTER PROGRAMME

摘要

The invention concerns a method for transmitting data in differential mode on a two-wired link using a common attenuation mode, corresponding connection device and computer programme. The invention concerns a method for transmitting data in differential mode on a link comprising at least two conductors, to a receiver equipment, for attenuating the effects of the common mode. In accordance with the invention, such a method includes a step of attenuating at least one common mode signal interfering with said data transmission, which consists, on each of said conductors, in: estimating by adaptive filtering of said common mode signal carried on said conductor; determining at least one parameter adapting said conductor, for reconstructing said common mode signal estimated on said conductor; injecting in phase opposition said common mode signal reconstructed on said conductor.
