VISIBLE LIGHT COMMUNICATION TRANSCEIVER AND VISIBLE LIGHT COMMUNICATION SYSTEM

摘要

Provided is a visible light communication transceiver. A drive amplification module performs digital-to-analog conversion and amplification on a digital modulation signal to obtain a first electrical signal, and transmits the signal to a Bias Tee-like circuit. The Bias Tee-like circuit transmits the first electrical signal to a LED light source. The LED light source performs electrical-to-optical conversion on the first electrical signal to generate a first optical signal and transmits the first optical signal, and performs optical-to-electrical conversion on a received second optical signal to obtain a second electrical signal. The Bias Tee-like circuit obtains the second electrical signal from the LED light source, and transmits the second electrical signal to an adaptive amplification and equalization module. The adaptive equalization module adjusts a gain of the second electrical signal based on an optical power of the first optical signal.
