Abstract
In the next generation digital terrestrial television broadcasting (DTTB) for mobile terminal, high data rate transmission is required to provide high definition image quality. Radio modulation format will be higher order digital modulation than current scheme. And the multiple antenna techniques will be employed for increasing data rate. This paper focuses on the gap-filler system using the radio over fiber (RoF) technique, which is currently employed for providing broadcasting service at radio dead zone such as underground city and in tunnel space. In this paper, system configuration is assumed next generation broadcasting signal with minimal modification from current system. The gap-filler system receives broadcasting signal at a fixed antenna and re-radiate after RoF transmission. The relationship between modulation error ratio (MER) at a mobile TV receiver and received RF power at fixed reception is evaluated by using computer simulation.
