Description

technical field [0001] The present invention relates to a visible light communication technology, in particular to a neural network equalizer based on visible light communication. technical background [0002] In recent years, semiconductor lighting technology known as "green lighting" has developed rapidly. Compared with traditional lighting sources such as incandescent lamps, LEDs have the advantages of low power consumption, long life, small size, and environmental protection. At the same time, LED has the advantages of good modulation performance and high response sensitivity. The signal is loaded on the LED with a high frequency that cannot be recognized by the human eye for transmission, and then a technology that can realize the integration of lighting and communication - visible light communication. [0003] Compared with traditional infrared and wireless communication, visible light communication has the advantages of high transmission power, no electromagnetic in...
