| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper discusses wireless train radio communications for high speed railway systems. Problems of wireless train radio communications are as follows: 1) to achieve higher transmission efficiency; 2) to cope with faster mobile speed; 3) to achieve longer distance between adjacent base stations. In order to cope with these problems, this paper proposes communication systems employing single frequency network, differential encoding / multiple differential detection with channel prediction, and two-subcarrier modulation scheme with half symbol period timing offset for the problems 1), 2) and 3), respectively. Finally, this paper compares the proposed scheme with the conventional scheme by computer simulation. At relatively good signal-to-noise ratio (SNR) and mobile speed of 300km/h, computer simulation results show the proposed system can cope with twice longer distance between adjacent base stations than the conventional system, while it suffers from 1.8dB peak-to-average power ratio (PAPR). | |
