超短波信道建模方法

摘要

Aiming at the complexity of the VHF channel and the lack of relevant mature method and model,the current domestic and existing models of the VFH channel and the channel modeling method are reviewed and summarized. The VHF propagation characteristics,channel parameters and existing model are introduced briefly. The modeling method which can be used for VFH channel on different application scenarios is focused,the method of the Stochastic Propagation Graphs are focused mainly and the validation of model based on the channel parameters are summarized. Finally,according to the application conditions,the related methods are discussed.%针对超短波信道传播条件复杂，缺乏相关成熟方法和模型的现状，对当前国内外现有超短波信道模型和建模方法进行了梳理、总结和归纳。简单介绍了超短波传播特性、信道参数以及现有模型，重点梳理了在不同应用场景下，可用于超短波信道建模的方法。然后，针对基于随机传播图理论的方法进行了重点介绍，总结了基于信道参数的模型验证方法。最后，针对不同的超短波应用条件，对相关的方法进行了展望。
