Abstract
Multilevel transmission of the CMOS image sensor-based visible light communication to improve the data capacity causes some problems, such as increasing the transmitter (Tx) complexity, indicating the nonlinearity at Tx, and creating the requirement for a precise thresholding method in the receiver. We propose an optical pulse width modulated multilevel transmission scheme based on binary-level signaling in the Tx to relax these problems. We experimentally demonstrated nine kbps error-free light-emitting diodes visible light wireless transmission using a CMOS image sensor and binary-level Tx in the proposed schemes.
