Abstract: Based on the Rytov approximation theory, the analytical expression for the scintillation index of multiple beams propagating through non-Kolmogorov turbulence is derived, where the incoherent combination is considered. The intensity fluctuation and bite error rate (BER) of the on-off-keying modulated multilayer radial beam array are studied. The results show that with a given beam array radius, the scintillation index and BER can be reduced by adjusting the layer number of the beam array and the beam number on each layer.
Keywords: Rytov Approximation Theory; Scintillation Index; Intensity Fluctuation; Multilayer Radial Beam Array; BER
