Abstract

ABSTRACT Simulation of Asymmetric digital subscriber line (ADSL) using the Discrete Wavelet Multitone Modulation (DWMT)

The Multi-Carrier Modulation is a technique used in breaking up the frequency spectrum into multiple sub-carriers, each of which is orthogonal to the other sub-carriers. The discrete multi-wavelet transform (DMWT) reduces the computation complexity and improves the performance efficiency. Most of the multi-carrier transmission systems use different techniques such as OFDM and single-carrier modulation techniques such as QAM for the ADSL technology. The bit error rate is poor, and the performance, flexibility, compatibility, and operational issue may arise during the information transmission. The DMT techniques combined with the ADSL can overcome these problems. The DMT partitions a broadband channel into many virtually independent, narrowband subchannels and maximizes the ADSL system's bit rate. The implementation of wavelets in the ADSL system improves the suitability, flexibility, and complexity of the multi-tone ADSL system. The paper compares the existing ADSL system problems with the DMWT-ADSL system. The main objective of this project work is to comparatively study the traditional multi-tone ADSL with the DWMT-ADSL, which provides a clear understanding of the application of wavelets in the broadband communication system. This paper is intended to share the results of the study. The method used is via simulation using MATLAB Simulink programs. We performed a detailed study of the ADSL system. The result of the simulation of the ADSL provides a broad view of how it works and transmits the data over the AWGN channel and demonstrates and documents the bit errors. The BER is the performance metrics compared using Meyer, DB-2 wavelets where the DB-2 shows low BER.
