Adaptive beam steering reception system for ISDB-T based on pre-FFT diversity technique

Generally speaking, the reception of high bit rate transmissions such as high definition television (HDTV) in automobiles is poor. In this study, we developed an adaptive beam steering reception system and experimentally investigated the performance of this new system on a mobile terminal for HDTV reception. The experimental results show that the reception quality was significantly improved by the new system. It was found that by using the adaptive beam steering technique we can expect good performance of HDTV reception on an automobile across a larger area.
