Performance of Wireless Optical Communication in [Formula Omitted]-Distributed Turbulence

A wireless optical communication (WOC) system is considered under [Formula Omitted]-distributed atmospheric turbulence. The [Formula Omitted]-distribution incorporates the line-of-sight (LOS), scattered and not coupled to LOS, and scattered but coupled to LOS (SCLOS) components of the propagating laser beam. The inclusion of SCLOS component provides more generality in modeling wider range of turbulence. The statistics of the instantaneous received signal-to-noise ratio (SNR) are derived for [Formula Omitted]-distributed WOC channel. Using the derived statistics, the outage and error performances of considered WOC system are investigated. Specifically, the new expressions for the outage probability and average bit error rate (BER) are obtained for various binary signalling techniques. Finally, the ergodic capacity performance is evaluated using numerical methods.
