Title: A proposed implementation of Digital Terrestrial Television (DTT) case study: Ashanti Region-Ghana
Authors: Siaw, Ntow Jerry
Issue Date: 21-Jul-2013
Abstract: Analog to digital television transmission is the transition from analog broadcasting to digital broadcasting. The International Telecommunication Union (ITU) has mandated every country to move from analog television to digital terrestrial television (DTT) by 2015. Ghana has chosen the Regional Rollout, where there is a move in phases through the regions. GBC (smart TV) has implemented a pilot project of the DTT in Kumasi and Accra. This thesis proposes the implementation of DTT in Ashanti Region, using the pilot project by GBC (Smart TV) in Kumasi, with aim of proposing a DTT that would give a full coverage in the Ashanti Region. In order to propose a way to give a full coverage with a good quality of service in the region, Smart TV Set Top Box (STB) and Skyy TV STB were taken to various areas in Kumasi and its environs. Parameters such as Bit Error Rate (BER), Signal to Noise Ratio (SNR)and Signal Strength (SS) were recorded by Smart TV STB and Skyy TV STB at various distances from their respective transmitters and were investigated using MATLAB. The values recorded by Smart TV was used to simulate the different modulation scheme using MATLAB and predicted that 8PSK was the best modulation scheme to be used by Smart TV in Ashanti Region. The research further provides simulation in terms of measured signals and theoretical values of three propagation models. Based on that the Rec. ITU P.370 propagation model was proposed for the region by comparing to free space model and Okumura model, additional new sites were also proposed for the smooth transition in Ashanti Region.
