To receive terrestrial digital broadcasting signals in an automobile, we previously proposed a method for controling the antenna directional pattern and demonstrated the effectiveness of the method by field experiment in an urban area. We have now investigated the reception quality during high-speed traveling and clarified the performance of doppler-shift compensation in the proposed method. A field experiment demonstrated that high-definition television (HDTV) signals can be received in an automobile traveling at about 100 km an hour.
