    DVB-T2 broadcasting with a single frequency network allows an efficient management of frequency utilization and extend the coverage area, which will enable more people to view a broadcast. The SFN mode also increases the concentration of the signal in overlap areas. However, some different of overlap areas in actual use of SFN networks may have some degradation of the received signal due to the effect of the SFN. In this research, we analyze SFN broadcasting in SISO mode. This paper represents the effects of delays on the SFN signal over different delay times within the guard interval by analyzing the minimum reception threshold. The analysis of received signal power, MER, bBER, LBER, and noise margin are studied using an actual digital television transmitter for the experiment. The results show that the minimum thresholds for a delay time at 0 microseconds will require higher receive signal power than other delay times within the GI. The results of this experiment are useful in designing the SFN network and make it possible to determine the appropriate C/N threshold for the design of the digital terrestrial television network.

    The performance of propagation analysis of DVB-T2 (Digital Video Broadcasting - Second Generation Terrestrial) is very significant for digital television broadcasting. That will analyze the effectiveness of the setting parameters that use for suitable of broadcasting. This paper provides the performance evaluation of DVB-T2 for fixed reception by the received signal measurement. The field measurements were taken in Bangkok of Thailand, along 20 locations. The receiver used to analyze the DVB-T2 signal providing several quality measurements (Power, C/N, MER, BER, constellation diagram, etc.).The results of the study could be useful for the improvement of DVB-T2 broadcast such as transmitter adjustment and gap filler transmitter installation to optimize the efficiency of digital television broadcasting.
