Abstract :
The author considers high-speed direct-detection optical on-off keying transmission in the physical layer of indoor wireless data networks and provides analytical tools to reveal the relationships between bit error rate, transmission rate, power, system and channel parameters, various noise sources, and multi-path effects. Both direct-path and diffused propagations are possible for successful transmission. Further, practical design issues such as blocking, optical pulse duration, and timing jitter are described. Typical numerical results are presented. The information-theoretical capacity of an indoor Gaussian channel with multipath is also calculated to illustrate the fundamental limit for adopting this approach
