Abstract(in English) | To increase data rate and security at the physical layer of space division multiplexing uplink optical camera communication from a smartphone screen to indoor camera, reduction of white light luminance on the screen has been done. In this study, we aim to realize improvement of the data rate and low luminance further by reducing white light cell size without changing the luminance. Reduction of white cell size can also suppress spatial inter symbol interference. Error-free transmission of 300 kilo symbol/s is achieved at high luminance 255 by reducing the white light cell size at 100x100 cells. In addition, the same received pixel value distribution as that of low luminance 95 is obtained by reducing the white light cell size at medium luminance 127. |
