论文摘要
当信号通过森林地区传播时，它们将受到植被等环境因素的影响。不同类型的环境对信号衰减有不同的影响。本文分析了现有的经典传播路径损失模型和森林区域引起的过剩损失的模型，然后提出了一种新的短距离无线通道传播模型，该模型可应用于不同类型的森林环境。我们在不同类型的森林区域的预定路线上以605 MHz的中心频率进行了连续的波测量，并记录了接收到的参考信号。然后，我们使用各种路径损失模型根据不同的植被类型和分布来符合测量数据。仿真结果表明，与代表性的传统同行相比，所提出的模型具有合理的计算复杂性拟合误差，其拟合误差较小。
When signals propagate through forest areas, they will be affected by environmental factors such as vegetation. Different types of environments have different influences on signal attenuation. This paper analyzes the existing classical propagation path loss models and the model with excess loss caused by forest areas and then proposes a new short-range wireless channel propagation model, which can be applied to different types of forest environments. We conducted continuous-wave measurements at a center frequency of 605 MHz on predetermined routes in distinct types of forest areas and recorded the reference signal received power. Then, we use various path loss models to fit the measured data based on different vegetation types and distributions. Simulation results show that the proposed model has substantially smaller fitting errors with reasonable computational complexity, as compared with representative traditional counterparts.
