High-speed, image-sensor visible light communication using rolling shutter has been studied. Symbol synchronization method by sequential estimation is applied to the line scan sampling using the rolling shutter of the image sensor and achievable symbol rate is simulated. Over 1400 symbols per second can be realized by the symbol synchronization at the frame rate of 30 fps with a QVGA screen. Acceptable...
Full-duplex visible light communication over a wide angle range is experimentally investigated using wide-angle LED and image sensor under fluorescent light condition. Isolation characteristics of more than 147 dB between received signal and other transmitted, reflected, and background lights are quantitatively estimated in the field of view of 70 degrees. Error free operation of full-duplex OOK visible...
