Abstract:To research the technologies and performances of the satellite mobile communications systems, it is necessary to know
the physical channel characteristics. In this paper, itconcretely analyzes satellitemobile communication channelpropagation character-
istics throughmultipath effects, shadowing effects, Doppler effects, ionosphere glitter and other aspects, and Rayleigh channelmode,l
Rice channelmode,l lognormal channelmode,l Loomode,l Corazzamode,l Lutzmode,l a five-stateMarkovmodelare studied from the
aspects of single-state statisticalmodel andmulti-state statisticalmode.l At last, it expects the research of future satellitemobile c
om-
munication channelmodels.
Key words:satellitemobile communication; channel characteristics; channelmodel
