| Abstract: | Based on the statistical model classification of mobile satellite communication channel,a partial-shadowing extended model suited for mobile satellite channel is proposed. The parameters contained in the model are given by means of trial and error,the model given can be used for nongeostationary orbits channel with varying elevation angles.BER performance is analyzed for narrow-band modulation and wide-band spread spectrum modulation in nongeostationary orbits communication systems,and some useful conclusions are drawn. |
