针对不同的紫外光通信模式,提出了非直视单散射信道模型的简化模型,通过实验验证了简化模型的准确性和高效性;在简化模型的基础上,对各种典型天气条件下,不同通信距离的能量损耗等进行数值仿真和结果分析,为日盲段紫外光散射通信系统的能耗分析提供了理论依据。通过对仿真结果的分析可知,简化模型可在保证仿真精度的前提下,提高仿真速度105倍;通信距离较小时,能见度对能量变化的影响较小;当距离增大后,薄雾天气对能量衰减迅速增加;随着距离的增加,轻霾、晴朗、非常晴朗等天气对能量衰减影响程度的差异也逐渐增加,即能见度越低,能量衰减曲线越陡,反之,曲线越平缓。
Aiming at different UV communication modes, a simplified model of non-direct-view single-scattering channel model is proposed. The accuracy and efficiency of the simplified model are verified by experiments. Based on the simplified model, The energy loss of communication distance and so on are simulated and the results are analyzed, which provides a theoretical basis for the energy consumption analysis of the solar blind scattering system. Through the analysis of the simulation results, we can see that the simplified model can improve the simulation speed 105 times under the premise of ensuring the simulation accuracy; when the communication distance is smaller, the visibility has less influence on the energy variation; when the distance increases, With the increase of distance, the difference of the influence degree of light haze, sunny and very sunny weather on the energy decay gradually increases, that is, the lower the visibility, the steeper the energy decay curve, on the contrary, the more gentle the curve.
