Infrared transceiver for digital communication / Nuhairi Mat Rahik

This project involves the design, operation and analysis of an infrared transceiver. The transceiver was designed to transmit data over a free space. The system is known as the 'infrared transceiver for digital communication'. In the thesis, the design methodology is described in detail starting from the theoretical concept to the working circuit design. The system consists of a transmitter and receiver. The optical beam emitted by the transmitter spreads in space or air, mainly in a forward direction. The receiver in a particular distance should detect the beam. Results are presented in maximum distances obtained between the transmitter and receiver, maximum input frequency of the system and optical power produced based on angular orientation. The proposed data rate of the transmission is 5Mbps.
