近岸海陆结合场景6GHz以下频段无线信道测量与建模
Measurement and Modeling of Wireless Channels in Sub-6GHz Bands for Nearshore Land-Sea Combined Scenarios
摘要
Abstract
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.关键词
