基于椭球模型的射线跟踪地空信道模型研究
Research on ground-to-air channel model for raytracing based on elliptical model
摘要
Abstract
Transport environment of wideband air-to-ground channel is very complex,and there are many factors to impact on designing air-to-ground communication system, such as multipath fading, multipath delay, fading rate,DOA, coherence time and so on. It used ground-to-air elliptical channel modeling,and obtain the elevation, transmission delay of LOS signal and maximum delay of multipath signal at this elevation from actual messurement and statistics of datum. By a series of calculation, its random DOA and random delay were solved. Then these datum were substituted into raytracking model,and simulated the channel The method of modeling reduced calculation and improved the simulation speed. The simulation results prove that theoretical analysis model agree with the simulation result,which is close to the actual channel.关键词
