Abstract :
In this paper, we present a finite-granularity rate-adaptive loading algorithm for a discrete-multitone (DMT) modulation system. The proposed algorithm is a performance increase of the P.S. Chow and Hughes-Hartogs algorithms. In fact, it is shown to be an important simplification of the P.S. Chow algorithm, and an optimal, flat energy distribution, starting solution to the Hughes-Hartogs one. Simulation results of a very-fast digital subscriber line (VDSL) transmission over twisted pair lines are presented.
