| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In ISDB-T (Terrestrial digital TV broadcasting in Japan), Orthogonal Frequency Division Multiplexing (OFDM) is adopted as a modulation scheme. The communication performance of OFDM is known to be superior especially to that of a single carrier in a multipath environment. However, multipath fading caused by many reflected signals seriously deteriorates the quality of digital communication at the mobile reception in actual fact. For overcoming this problem, to perform beam-forming and null-steering adaptively by adaptive array antenna technology reduces the effect of fading. It enables the stable reception even if radio environment changes with time at the mobile reception. In this paper, we propose the system configuration in consideration of antenna directivity when four antennas are mounted on a vehicle and we experimentally demonstrate that the ISDB-T is a superior reception performance when OFDM signal arrives with delay exceeding the Guard Interval length. | |
