Experimental Study Based On RGB LED Visible Light Communication
In order to realize the functions of illumination and communication of the visible light communication (VLC) technology, pulse position modulation (PPM), color shift keying (CSK) and hardware algorithm field programmable gate array (FPGA) are combined to verify experimently the proposed RGB chaotic pulse position modulation (CPPM) based on RGB LED application. The constant current drive circuit at the transmitting terminal, the optical antenna module, LED heat management and each signal-processing circuit module are designed in the system. The circuit performance is verified by testing. The parameters, including waveform, bit error rate (BER), illumination and others, are analyzed. The feasibility and practicability of the system are validated.
