Resumen : In this document the presence of shaded areas is determined by applying three interpolation algorithms, called: Natural Neighbor Interpolation, Linear Interpolation and Nearest Neighbor Interpolation; individually executed in a computer program created within the GUI environment MATLAB. Measured points are interpolated in terms of field strength and MER, taking into account the reference levels established in accordance with the Technical Standard for the broadcasting of Digital Terrestrial Television in Ecuador and specifications recommended by the ISDB-Tb adopted by the country. The results will be presented in the virtual map provided by Google Earth software, which facilitates the representation of the signal level that will serve to display shaded areas and an analysis of the results and validation of each interpolation algorithm is performed by error calculations. Additionally, a coverage prediction software in ICS TELECOM be performed with models P.1546 and ITUR ITU-R P.1218 propagation, to compare actual measurements taken at various points within the selected measurement area with those estimated by the software.
