Summary:
From the viewpoint of frequency utilization efficiency, SFN (single frequency network) is an essential technology for the digital terrestrial TV broadcasting in Japan. We focus on the on-board SFN re-transmission system developed by one of us. Since this system is influenced by the coupling wave, it is important to evaluate the broadcasting signal quality which is often evaluated by the equivalent C/N degradation. However, the existing method cannot be applied to the system, because it does not consider delay wave components over the guard interval (GI) caused by coupling wave. In this paper, we derive the calculation equations to evaluate the equivalent C/N degradation correctly.
