Effect of Receiving Antennas Radiation Pattern on an SFN Network Coverage This article presents the results of a series of simulations that aim to analyze the impact of using different receiving antennas in the coverage area of a Single Frequency Network (SFN) under the Advanced Television Systems Committee (ATSC) standard. The purpose of this study is to compare the coverage deployed by an SFN network in Mexico City, with three different configurations of receiving antennas for end users based on the use of omnidirectional and directives antennas. The directives antennas attenuate signals that arrive from different directions of the main pointing direction, so they can attenuate the signal radiated from the second transmitter of the SFN, decreasing the selfinterference in the network and making easier the reception.

Methodology for Analyzing ATSC 3.0 Single Frequency Network Overlapped Area Based on Spatial Interpolation In extending the single frequency network (SFN), it is inevitable that the newly added broadcasting stations are established while the existing broadcasting stations are being operated. To identify the SFN signal overlapped area before and after the construction and to check whether the newly added transmitter signals are stably interoperable to those of the existing transmitters without selfinterference, the measurement vehicle should be fixed at a certain measurement point and the transmitter must be turned on and off uptodate. Hence, as the number of fixed measurement points increases, the transmitters will be exposed to severe stress. Additionally, because the fixed measurement takes a long time to collect enough volume of data, it is not practical to use the old technology as it is. In this study, we propose a novel method to collect the field test data by mobile measurement under the fixed transmitter condition, i.e., turned on or off. Then, the difference between the two results is calculated using data processed by spatial interpolation to determine the SFN signal overlapped area quickly. After applying this to field test data, it is confirmed that coverage of each transmission site obtained by the proposed method is almost identical to that of the coverage prediction and planning software.
