摘要

现代自由空间通信系统需要对大气湍流如何影响闪烁指数和误码率（BER）进行综合分析。本文建立了超洛伦兹高斯光束（slgb）在发射和接收平面间斜传播的激光模型。由于惠更斯-菲涅耳法能准确模拟大气湍流，因此采用该方法计算接收场。天顶角为50°时，轴上闪烁指数最低。在此分析中，接收面孔径大小起着至关重要的作用。当孔径面积占接收面面积的25%时，SLGB00的闪烁指数最低。在激光波长为1.55µm时，SLGB22的闪烁指数接近SLGB00。我们将接收孔径减小到1.4 × 10−3%，并计算了SLGB00和SLGB22的轴上闪烁指数和误码率。SLGB22的轴上闪烁指数和误码率最低。

Computation of the scintillation index and BER of super Lorentz Gaussian laser beam in a slant propagation at atmospheric turbulence

Modern free-space communication systems require a comprehensive analysis of how atmospheric turbulence impacts the scintillation index and the bit-error rate (BER). In this paper, we model the laser light with Super Lorentz Gaussian Beams (SLGBs) intensity distribution slant propagation between the transmitter and receiver planes. The Huygens-Fresnel Method is employed to compute the received field due to its effectiveness in accurately modeling atmospheric turbulence. A 50° zenith angle results in the lowest on-axis scintillation index. The receiver plane aperture area size plays a crucial role in this analysis. For an aperture area that covers 25 % of the receiver plane, the SLGB₀₀ almost exhibits the lowest scintillation index. The SLGB₂₂ scintillation index approaches SLGB₀₀ at a laser wavelength of 1.55 µm. We reduced the receiver aperture area to 1.4 × 10⁻³% and computed the on-axis scintillation index and the BER for both SLGB₀₀ and SLGB₂₂. SLGB₂₂ shows the lowest on-axis scintillation index and BER.
