Abstract :
This article describes the near-far problem in the upstream direction of VDSL, which results when the lengths of VDSL loops in a binder vary significantly. Methods of upstream power backoff to mitigate the near-far problem are then described. Simulation results are presented, and the performances of the methods are discussed
