海洋通信是6G空天地海一体化网络的关键场景。海洋信道特性分析与建模对海上通信系统的技术开发和部署规划具有重要意义。关注海岸边的岸-船通信场景，介绍了在 5。80、5。45、3。90、3。00 GHz频段开展的无线信道测量活动，提取并建模了岸边发射机与运动船舶之间无线链路的关键信道参数。研究发现存在于近岸区域的散射体以及沿海岸线分布的建筑群会对信道造成差异化影响。基于实测数据给出了时变抽头延迟线(Tapped Delay Line，TDL)架构参数化模型。针对多径分量丰富的近岸区采用 5 抽头模型，并通过设置随机时变抽头表征了场景中偶然存在的高时延多径分量。仿真结果与实测数据概率密度分布的科尔莫戈洛夫-斯米尔诺夫检验(Kolmogorov-Smirnov，K-S)统计量为 0。11，KL散度为 0。65，研究结果可为近岸场景岸-船通信技术的设计和部署提供参考。
Measurement and Modeling of Wireless Channels in Sub-6GHz Bands for Nearshore Land-Sea Combined Scenarios
Marine communications are a key scenario for the 6G air,space,ground,and sea integrated network.Analysis and model-ing of ocean channel characteristics are of great significance for the technological development and deployment planning of maritime communication systems.Focusing on the shore-to-ship communication scenario along the coast,wireless channel measurement activities were carried out in the 5.80,5.45,3.90,3.00 GHz frequency bands.The key parameters of the wireless link between the shore trans-mitter and the moving ship were extracted and modeled.The study found that scatterers in the near-shore area and buildings along the coastline have differential impacts on the channel.Additionally,a time-varying Tapped Delay Line(TDL)architecture parameterized model was developed based on the measured data.A 5-tap model is adopted for near-shore areas with abundant multipath components,with random time-varying taps set to characterize the high-latency multipath components that occasionally exist in the scene.The Kolmogorov-Smirnov(K-S)statistic of the probability density distribution between the simulation results and the measured data is 0.11,and the KL divergence is 0.65.These research results provide valuable references for the design and deployment of shore-to-ship com-munication technology in near-shore scenarios.
