Abstract :
The feasibility of using adaptive transmitter-receiver combinations on several pairs in the same cable to suppress mutual crosstalk is investigated. It is shown that using optimized block codes of insufficient length results in unstable adaptation of the transceivers and concomitant severe transmission distortion. However, if the code blocks are greater than a certain critical length determined by, among other things, the number of pairs involved, near-end crosstalk can be completely eliminated
