摘　　要：针对电磁波海上传播的特性,在SPM的基础上提出一种改进的海面传播模型,同时提出一种基于WLS算法的传播模型校正算法,并利用琼州海峡海面CW测试数据对改进SPM参数进行校正。根据校正后的传播模型,利用琼州海峡海岸现有基站对NB-IoT覆盖进行链路级仿真和覆盖仿真。实验结果表明,所提方法能有效地实现对琼州海峡的NB-IoT覆盖,对于NB-IoT网络实际部署具有指导意义,有助于海上物联网的科学研究。Based on the standard SPM, an improved sea surface propagation model was proposed. At the same time, a propagation model correction algorithm based on WLS algorithm was proposed. Using the CW test data of Qiongzhou Strait, the parameters of the improved SPM were corrected. Based on the corrected propagation model, the current base station of Qiongzhou Strait coast was used to carry out link level simulation and coverage simulation for NB-IoT. The experimental results show that the proposed method can effectively achieve the coverage of NB-IoT in Qiongzhou Strait and contribute to the scientific research of Internet of things.
