Outage capacity of mobile wireless optical link in indoor environment
Résumé
In this paper, we investigate the potentiality of a wireless optical communication system in an indoor environment for both line of sight (LOS) and diffuse configurations by taking into account transmitter mobility. Statistical model of the mobile optical channel is defined for each configuration. Our contribution is to determine the outage probability and then the outage capacity considering an On-Off Keying modulation and different data rates. From the results one can obtain the outage probability value which maximizes the outage capacity for the considered indoor mobility scenario. We finally show the LOS performance gain provided by Forward Error Correction (FEC), considering Low-Density Parity-Check (LDPC) codes of different lengths.
