How does atmospheric turbulence affect threshold detection in optical channels?
Abstract
Optical communication through the earth's atmosphere offers a great contribution in increasing data transmission capability. In addition to background radiation and photodetector random gain, the performance of such a channel is highly affected by atmospheric turbulence along its propagation path. In this article, threshold detection for this channel is studied under different turbulence levels, concluding the optimum threshold setting for different alphabet sizes.
