VISIBLE LIGHT COMMUNICATION TRANSCEIVER AND VISIBLE LIGHT COMMUNICATION SYSTEM

摘要

Disclosed in the present application is a visible light communication transceiver. The visible light communication transceiver comprises an LED light source, a Bias Tee circuit, a driver amplifying module and a self-adaptive amplification equalizing module. The driver amplifying module is used for performing digital-to-analog conversion and amplification on a digital modulation signal to obtain a first electrical signal, and the first electrical signal is transmitted to the LED light source by the Bias Tee circuit; the LED light source is used for performing electrical-to-optical conversion on the first electrical signal to generate and transmit a first optical signal, and performing optical-to-electrical conversion on a received second optical signal to obtain a second electrical signal; the Bias Tee circuit is used for obtaining the second electrical signal from the LED light source and transmitting the second electrical signal to the self-adaptive amplification equalizing module through a radio frequency port; and the self-adaptive equalizing module is used for adjusting, according to the optical power of the first optical signal, the gain of the second electrical signal to obtain an electrical signal corresponding to the second optical signal. According to the visible light communication transceiver of the embodiment of the present application, optical signals can be transmitted and received simultaneously.
