The Development of a LAN for DVB-T Transmission and DVB-S Reception with Designed QAM Modulators and COFDM in the Island Mauritius

TL;DR

This study designs and tests DVB-T and DVB-S digital broadcasting systems with QAM modulators and COFDM in Mauritius, demonstrating feasibility and performance considerations for island deployment.

Contribution

It introduces a tailored digital LAN system for Mauritius using DVB-T and DVB-S with designed QAM modulators and COFDM, validated through simulation under realistic conditions.

Findings

DVB-T with QAM-64 and QAM-16 is feasible in Mauritius.

QAM-16 performs better under low AWGN conditions.

Single frequency network transmission is achievable in Mauritius.

Abstract

This paper is a thorough study of a digital broadcasting system adapted to the small mountainous island of Mauritius. A digital LAN was designed with MPEG-2 signals. The compressed signals were transmitted using DVB-T and QAM modulators. QAM-16 and QAM-64 modulators were designed and tested with a simulator under critical conditions of AWGN and phase noises. Results obtained from simulation have shown that Digital video broadcast with a single frequency network (SFN) is possible in Mauritius with QAM-64 and QAM-16 modulators applying COFDM mode of transmission. However, this study has also shown that QAM-16 modulator had a better performance at low AWGN values (less than 12 dB) and can be adopted for Mauritius Island, provided that the number of transmitted channels is not high enough.
