Abstract
We propose, for the first time to the best of our knowledge, a novel non-line-of-sight 2×N indoor optical camera communication system, where N is the number of pixels in the camera with a unique packet structure and a detection methodology for extracting the data from the recorded video streams. A comprehensive theoretical model for the proposed system is presented. The proposed system is experimentally investigated, and the measured results show that higher International Standards Organization (ISO) levels and exposure times lead to a reduced transmit power level by 3dB for every doubling of the exposure time and ISO at a bit error rate of 10-3. It is also shown that when the overlapping area of two interfering transmitters is larger than approximately 30% of the footprints, the data cannot be recovered.
