communication system (OWC) employing M-ary pulse position modulation (PPM) scheme in
anisotropic non-Kolmogorov turbulent atmosphere is investigated. Avalanche photodetector
(APD) is used at the receiver side and log-normal channel that models the weak turbulence
conditions is utilized. Anisotropy, generally resulting in better performance in OWC systems
operating in the turbulent medium, combined with the adaptive optics applications will …
