Gamma Function Based Signal Compensation for Transmission Distance Tolerant Multilevel Modulation in Optical Camera Communication

Gamma Function Based Signal Compensation for Transmission Distance Tolerant Multilevel Modulation in Optical Camera Communication

Data rate of optical camera communication is limited by low frame rate of the CMOS image sensor, so that multilevel modulation is required to improve its data rate. However, transmission performance may decrease with varying transmission distance between LED and image sensor due to nonlinearity occu...
