Planteamiento de una metodología para la determinación de posibles zonas de sombra mediante algoritmos de interpolación en la banda de frecuencias UHF de TDT (TELEVISIÓN DIGITAL TERRESTRE)

Abstract

This project aims to determine the existence of areas of shade in the broadcasting of DTT (Digital Terrestrial Television) for the channels currently operating in the city of Quito, for this interpolation algorithms are used, which allow calculation of unknown measurements from other already made. Measurements are made correspond to electric field intensity and MER (Modulation Error Ratio), these measurements are received by the equipment: Rohde & Schwarz ETH and ARGUS Software of the Mobile Station SACER (Automatic Control Spectrum radio) of ARCOTEL (Agency for Regulation and Control of Telecommunications). For interpolating the midpoints three algorithms are used, called: Natural Neighbor interpolation, Nearest Neighbor Interpolation and Linear Interpolation, arranged in MATLAB (Matrix Laboratory), where it is implemented data adaptation mechanisms, conversion of units and creating arrays, to make a simulation of coverage on the virtual map Google Earth program to determine the existence of areas of shade; also a tool in GUI (Graphical User Interface) that facilitates the user to use the program is done.
