A novel low complexity linear precompensation technique for multi-user DSL Transmissions

Résumé

Crosstalk is the major source of performance limitation in the current short range DSL systems. Coordination between users in the downstream and in the upstream directions has been recently proposed in order to overcome the effects of FEXT in DSL transmissions. In this paper, we study a new low complexity precompensation solution for FEXT reduction for such systems. It is compared to the ideal precompensation technique as well as to a simplified existing solution based on Jacobi development. The proposed precompensation technique presents the same complexity but has better performance than the Jacobi based precompensation solution. The obtained performance is closer to the optimal data rates resulting from a perfect FEXT precompensation.
