Recently, discrete multitone modulation (DMT) technology has become extremely popular due to its efficient implementation, which uses fast Fourier transforms (FFTs) to modulate and demodulate transmitted information across the asymmetric digital subscriber line (ADSL). A crucial aspect in the design of a DMT system for data transmission over spectrally shaped channels is the need to optimize the system transmission bandwidth through an optimal loading algorithm. In this letter, we propose a practical and efficient loading algorithm for DMT system. Simulation results show that the proposed algorithm converges fast than Chow's method with the loss of system margin.
