  1. It contributes to the deeper comprehesion of these probability distributions, affords more detailed theoretical basis for further studying and simulating satellite mobile channels, ? theoretical analyses and discussions of the models which are often used in the study of the propagating characteristics of satallite mobile channels are given ; meantime, some discussions on the work of model simulations are also given, ? incorrect derivation of the equality between c. loo model and corazza model in some other papers is pointed out. via the conception of received power, we derivate that in the rural environments these two models really have the equal relationship by the way of theoretical derivation and simulatant fittings. therefore, it is able to use corazza model in studying the characteristics of satellite mobile channels in the rural environments and able to avoid the iterant work of modeling, in order to enhance the efficiency and accuracy of research work, ? detailed processes of simulating lutz model by using matlab6. 0 _ simulink4. 0 and the results of comparisions are given

    本文包含有以下的主要內容: ?對衛星移動通信通道特性研究中用的三個概率分佈給出了詳細的推導過程;以便對這幾個在衛星移動通信通道特性的研究中用的概率分佈函有更深的理解,對進一步研究衛星移動通信通道特性和對通道的建模提供了更為詳盡的理論基礎; ?對衛星移動通信通道特性的研究中用的通道模型進行了理論上的分析和討論,並對衛星移動通信通道建模的研究工作提出了一定的看法; ?指出了以前的文獻中關于c . loo模型和corazza模型的等同性的證明誤;並從接收信號功率的角度出發,通過理論推導及模擬曲線擬重新證明了在鄉村環境下,這兩個模型的確是具有等同性的;從而在對鄉村環境下的衛星移動通信通道特性進行研究時,可以只採用corazza模型來對實際的通道進行建模,這樣可以避免重復的建模工作並提高研究工作的效率和準確性; ?給出了lutz模型在matlab6 . 0 _ simulink4 . 0環境下的軟體模擬實現的詳細過程和整體模擬測試的對比結果,保證了該模型在硬體實現時的可靠性和可行性,從而可以將它們應用於指導模型的硬體模擬實現並可以降低硬體實現時的風險。
