Transmission characteristics of a NLOS cloud-scattering channel

A stochastic non-line-of-sight(NLOS) cloud-scattering communication channel model is developed using a stochastic migration theory based on Monte Carlo simulation method, by which the expected path loss is obtained, when an optical signal with impulse in space and step in time incidence on a plane, parallel fixed, homogeneous cloud with given communication configurations. The crucial factors that affect the path loss is analysed theoretically. Multiple scattering effects of signal propagation in the atmosphere are taken into considerations. The advantage of proposed model in reliable prediction of NLOS cloud-scattering path loss is validated by field experiments under different communication configurations. These results involved are wavelength-independent, 620nm is chosen as the wavelength of experiment and simulation.
