METHOD OF CORRECTING THE PARA-CROSSTALK OF AN SDSL LINK

摘要

Device for correcting the para-crosstalk at an end of an SDSL link with N pairs of conductors. According to the invention, said device comprises, on the one hand, between a sender conductor of a pair i and a receiver conductor of a pair j, a correction module (ij) able to calculate the quantity h_ij(k)*x_i(k) where h_ij(k) is an estimate of the coupling function h_ij determined in accordance with claim 1 and x_i(k) the signal sent on the sender conductor of the pair i, and on the other hand, a subtractor (j0) able to subtract from the signal received on said receiver conductor of the pair j the quantity h_ij(k)*x_i(k) provided by said correction module (ij). Application to increasing the bit rate on multi-pair SDSL links.
