论文摘要
先前关于非视线(NLOS)紫外线通信(UVC)中单级传播的时间特征的研究是基于pral型晶状体坐标系。在这项工作中,在球形坐标系中提出了一种新型的单筛通道脉冲响应(CIR)模型,该模型比实际应用中的prate-Spheroidal坐标系统更自然,更可理解。此外,还提供了广泛接受的NLOS UVC的基于广泛接受的蒙特卡洛(MC)通道模型,以验证所提出的单碎片CIR模型。结果表明,所提出的单筛CIR模型所花费的计算时间降低至基于MC的单分体模型的0.7%,在评估NLOS UVC通道的时间特征方面具有可比的精度。
Previous studies on the temporal characteristics of single-scatter transmission in non-line-of-sight (NLOS) ultraviolet communications (UVC) were based on the prolate-spheroidal coordinate system. In this work, a novel single-scatter channel impulse response (CIR) model is proposed in the spherical coordinate system, which is more natural and comprehensible than the prolate-spheroidal coordinate system in practical applications. Additionally, the results of the widely accepted Monte-Carlo (MC)-based channel model of NLOS UVC are provided to verify the proposed single-scatter CIR model. Results indicate that the computational time costed by the proposed single-scatter CIR model is decreased to less than 0.7% of the MC-based one with comparable accuracy in assessing the temporal characteristics of NLOS UVC channels.
