Abstract
The indoor infrared optical communication system provide a useful complement to radio-based systems, particularly for systems requiring low cost, light weight, high rates, and nopollution. With peoples' increasing requirement for the rate and convenience of indoor communications,indoor infrared optical communications will be more and more impotrtant.
This paper describes the indoor wireless optical communicationsystem particularly after collect and refer to abundance literature information, learning abundance correlated principle of indoor wirelss opitical communication. Studies the channel characteristics, and simulates them with Matlab. Then based on that, a group of input/output signals are compared and analysed. Finally the problem of how does the background light noise affect the transmission are simply described, and some corresponding plans are proposed.
