面向远海场景的统计信道建模与性能分析
Statistical channel modeling and performance analysis for offshore scenarios
摘要
Abstract
Currently,research on maritime communications is predominantly focused on channel modeling in nearshore scenarios,with limited consideration of real meteorological conditions,and studies targeting offshore scenarios still require further improvement.In view of this,a statistical over-the-horizon channel model utilizing the maritime evaporation duct phenomenon is constructed based on the measured meteorological data from the Yellow Sea region of Shandong Province.In this model,a rational function framework is employed to describe the propagation characteristics of electromagnetic waves in the marine environment.Additionally,to enhance the accuracy of the model,the coefficients of the model are corrected and optimized with the nonlinear least square method.Simulation analysis demonstrates that the channel model provides more accurate prediction of electromagnetic wave propagation path loss in the surrounding maritime areas,with the root-mean-square error(RMSE)of prediction for both winter and summer being lower than those of the surface duct model and the free-space model.Moreover,it exhibits superior performance in UAV-assisted maritime communication systems.关键词
