| 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 we... |
