Abstract

A prototype indoor wireless optical transceiver system that uses LED as transmitting light source has been designed and developed. This wireless optical transceiver system can transmit ASCII-coded data for a distance up to 50 meters, and achieve a data rate of 230.4kbps. Huffman source coding with variable code words length is implemented as a compression technique so that data redundancy is minimised and spectral efficiency increased, and channel error-correction coding using Hamming linear block codes is implemented to counter the effect of noise during transmission.
