Optimization of Propagation Graph Modeling Methods for Dynamic Channels
摘要
Abstract
Dynamic channel modeling methods is an important aspect of the research and development of 6G.Propagation graph theory,a channel modeling method based on directed graph topology,is characterized by its computational efficiency and accurate de-scription of the power exponential decay of channel multipath,which can also better meet the needs of spherical wavefront model re-search and channel modeling in 6G.Responding to the practical needs of dynamic channel modeling for 6G scenarios,this paper sorts out the basic theory of propagation graph theory,summarizes and proposes a dynamic channel modeling framework and specific frame structure for dynamic scenarios based on propagation graph theory.The algorithm of propagation graph theory is optimized based on the reflected wave power mechanism,effectively improving the accuracy of channel simulation in complex environments.And the feasibility and performance improvement of this modeling method are validated by simulation and measurement.关键词
