Visible light communication (VLC) is an upcoming wireless technology for next-generation communication for high-speed data transmission.It has the potential for capacity enhancement due to its characteristic large bandwidth.Concerning signal processing and suitable transceiver design for the VLC application, an amplification-based optical transceiver is proposed in this article.The transmitter simply boho classroom consists of a driver and laser diode as the light source, while the receiver contains a photodiode and signal amplifying circuit.
The design model is proposed for its simplicity in replacing the trans-impedance and transconductance circuits of the conventional modules by a simple amplification circuit and interface converter.The system was tested at communication distances of 1m and 3.5m using a terminal emulation program synovex one grass for data transfer between two computing devices.
