Performance enhancement of an FSO link using polarized quasi-diffuse transmitter

Free space optics (FSO) system has received much interest in recent years as a technology that exhibits cost-effective, better security, license-free, and comprehensive capacity access techniques for transmission of Giga data rate. However, despite all the many advantages demonstrated by its signal,...
