| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we focus attention on the parallel optical wireless communication systems using LED array transmitter and high-speed camera as the receiver for road-to-vehicle communications in ITS. Previously, we proposed a hiearachical coding scheme which allocates data to spatial frequency components depending on the priority. This scheme is possible to receive the high priority data even if the receiver is far from the transmitter. However, since vehicles drive on a road in actual road-to-vehicle communications, it is difficult that synchronizing the timing to release the shutter with the lighting cycle of LEDs, namely, sampling of the data is important work. This paper proposes a sampling method for road-to-vehicle communications during driving and performs driving experiments using a car with the high-speed camera. Moreover, we not only analyze received images by off-line operations but also investigate future problems for the communication system design. |
