Joint influence of heterogeneous stochastic factors on bit-error rate of ground-to-ground free-space laser communication systems

摘要

Research methods for the formation of BER in the ground-to-ground Free-Space Laser Communication Systems (Free-Space Optics - FSO) with increased analytical effectiveness have been suggested. They correspond to physically rightful approximations with approbated quantity effectiveness. The methods have been used to study the influence of heterogeneous stochastic factors, such as: quantum noises, atmospheric transmittance fluctuations, mechanical vibrations of the transmitting laser antenna, atmospheric turbulence, on BER of FSO. An algorithm for quantity estimation of the joint influence of all stochastic factors has been created. Numerical examples, illustrated by graphic material, have been shown.
