| 摘 要： | 非视线(NLOS)光传输信道的研究目前常用单次散射近似方法,在进行较远距离、复杂天气条件下NLOS光传输模拟时误差很大,为此,本文提出并建立了一种基于蒙特卡罗方法NLOS光传输模型.研究表明,该模型与单次散射近似应用在近距离、天气条件好时NLOS传输的模拟结果比较吻合.进行了不同距离的NLOS光传输对比实验,结果验证了该算法的正确性和有效性.

| Abstract: | The single-scattering theory is always used to study the non-line-of-sight(NLOS) light propagation,but when it is used for long distance or under complicated weather,much larger error will occur.In the paper,the NLOS light propagation model based on Monte Carlo method is described in detail.This model is not only accordance with single-scattering model under short distance and clear weather,but also in good agreement with the comparative experimental results,which also illustrates the correctness and efficiency of this algorithm. |
