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.

DVBT2 Receiver: Impact of FFT Window Positioning on Radio Coverage In modern digital terrestrial broadcasting systems, Single Frequency Network (SFN) is a prominent technique used for improved spectrum efficiency, network gain, and increased flexibility. In an SFN, the placement and positioning of FFT window relative to the multiple received signals strongly affect the receiveru0027s behavior of handling InterSymbol Interference (ISI). Thus, the treatment of ISI in receiver further impacts on the radio coverage predictions and network planning. In this paper, the radio coverage due to a typical SFN network is evaluated and analyzed for different FFT window synchronization methods. This is repeated for different transmission and reception modes used in the next generation of broadcasting standards and systems specifically in the DVBT2 system.
