Model Establishment and Simulation Analysis of Visible Light Communication System

Aiming at the research status of visible light communication technology, a Lambertian model communication system based on visible light communication is designed in this paper. The power of the communication system under the Lambertian model is quantitatively studied, the power relationship of the transceiver under the direct link is constructed, and the signal-to-noise ratio of the system is theoretically analyzed. Fast Fourier Transform (FFT) spectrum analysis is performed on the receiver signal of superimposed Gaussian noise. Through Simulink simulation, the receiver waveform distortion of the communication system is low and has high communication quality.
