Abstract
In view of the existing wireless optical communication analysis, a single model of plane wave or spherical wave model is adopted when calculating turbulence model parameters without considering turbulence intensity and receiving aperture size, causing a large difference between two models among the actual gaussian beam, thus calculating the quoted error of scintillation index and signal-to-noise ratio (SNR) when using different models in different turbulence intensity in blue-green laser communication. The results show that the plane wave model has smaller error in weak turbulence, spherical wave model has smaller error in strong turbulence, but both models have larger error in medium turbulence. Therefore, plane wave model can be used to simplify the calculation in weak turbulence, spherical wave model can be used to simplify the calculation in strong turbulence, but any approximate models should not be used in medium turbulence.
