Patent ID: 8009574

Claim:
A method, wherein the following steps are iteratively repeated, comprising: providing each of a plurality of signals at a respective one of a plurality of transmission links, the transmission links being wired lines wherein neighboring ones of the transmission links are distorted by cross-talk interference; transmitting each of the plurality of signals over the respective one of the plurality of transmission links; and measuring signal-to-noise ratios of the plurality of signals transmitted over the plurality of transmission links, wherein an input power level of each of the plurality of signals is set such that the signal-to-noise ratios of the plurality of signals converge when measured after their transmission over the plurality of transmission links; wherein, at each iteration cycle, the input power level of each of the plurality of signals when provided at the respective one of the plurality of transmission links depends on the difference of the measured signal-to-noise ratio of the signal transmitted over the respective one of the plurality of transmission links during the previous iteration cycle and an average value of the measured signal-to-noise ratios of the plurality of signals transmitted over the plurality of transmission links during the previous iteration cycle.
