Abstract

Discrete multi-tone (DMT) modulation is an orthogonal frequency division
multiplexing (OFDM) based modulation scheme used in asymmetrical digital subscriber
line (ADSL) and proposed for various other high-speed broadband access systems. To
enhance the bit error rate (BER) for the DMT-ADSL, a discrete multi-wavelet transform
(DMWT) model is proposed. The performance of standard and proposed models is simulated
using Matlab software under the additive white Gaussian noise (AWGN) channel
effect. The effect of impulse random bit location noise was also taken into our simulation.
The simulation results show that the proposed model based on DMWT technique
outperforms the standard model in terms of BER.
