We propose a ground-to-train communication system using free-space optics between a train and the ground. In this paper, we evaluate BER characteristic in outdoor experiment using test train. The experimental results lead to the conclusion that the proposed system is a promising candidate for train communication from the viewpoint of BER characteristic.
To achieve high quality and reliability in mechatronics products, thorough consideration of dynamic performance in structural design is essential. Typical examples include the design of optical pickups for disk related products, such as Compact Disc (CD) drives, and Magneto-optical Disc (MO) drives. Many researchers have developed design methodologies to(More)
