Outline of Final Research Achievements |
This research subject has considered an image-sensor-based LED visible light communication (VLC) system using a portable illumination apparatus for lifesaving in a disaster situation. The sub-theme 1 has quantitatively analyzed a transmitted LED light affected by an obstacle such as rubble (i.e., communication channel). As results, I concluded that the size of the LED on the image is necessary more than one pixel to prevent the impairment of demodulation performance in the image-sensor-based LED VLC. The sub-theme 2 has proposed a novel demodulation scheme using characteristics of a degraded image, which is affected by the communication channel in the disaster situation. As results of a simulation and an experiment, I have confirmed that the proposed method has a better performance as compared with the conventional demodulation method.
