In this work, a simple and new method is proposed to simultaneously generate more complex chaotic waveforms, enhancing the complexity of chaos and the confidentiality of communication systems, by combining visible light communication system with chaotic signal. The effectiveness of the VLC system is investigated over a range of transmission distances and different chaotic signal with 700 THz operating wavelength and (10) Gbps data rate. The simulation results proved the efficiency of the encryption system in terms of complexity of signal and processing time in the transmitting side and return the signal in the receiving side after subtracting the chaotic signal. The results show that the co-simulation of VLC and chaotic signal using MATLAB and OptiSystem technology is better than the rest of the other techniques used in all types of modulation in terms of link range and bit error rate BER but that have higher processing time. In the system, two codes used to generate chaotic signal (using Lyapunov exponent code and using ANFIS code). The system performance in terms of bit error rate (BER) and Q factor enhanced also the processing time. The system is simulated using OptiSystem15 with a MATLAB2016. The chaos generation is now being utilized to improve data security and protect data from theft during its transmission from transmitter to receivers, a means of concealing multi-level data signals in order to address these concerns regarding data security.
