Abstract :
A prototype of the 1 Mbps nondirective infrared wireless transmission system was designed, and tested. The system design considerations such as the channel property, optoelectronics devices characteristics, and modulation schemes are discussed, and the circuit design and implementation are described. In this system, pulse position modulation (PPM) with short pulse duration and an analog-multiplier type demodulator were used. The feasibility of nondirective transmission is fully demonstrated, showing that it can support successful data communication in a typical room. The system architecture can be upgraded to data rates such as 2 Mbps or higher by only changing the circuit parameters
