  1. 7 hours ago · Free space optical communication (FSO) is designed using the orthogonal quadrature phase shift keying (OQPSK) modulation technique. The system performance is evaluated for various levels of atmospheric turbulence, transmitter power, beam divergence, transmitter and receiver aperture diameters, and atmospheric losses. In this paper, we evaluated the system parameters for atmospheric turbulence using the Gamma gamma turbulence model. The system is evaluated for atmospheric losses such as clear ...
