The Results of Mobile Reception Experiments for Digital Terrestrial Broadcasting on Bullet Train using Directional Diversity

Abstract

We have been studying on reception stably HDTV digital terrestrial broadcasting by a high-speed vehicle such as a Bullet train. We reported the analysis results of mobile reception experiments on a bullet train with 4-branch space diversity. In this paper, we reported the analysis results of mobile reception experiments on a bullet train by a space and directional diversity technique with diversity combining that uses array antenna having 2 elements. As a result, the time ratio for the space diversity method was 61.3%, and for the directional method was 57.5%, in the total of all measurement routs in a high-speed mobile reception environment on a bullet train.
