例句与造句
- 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内容： ?对卫星移动通信信道传播特性研究中常用的三个概率分布给出了详细的推导过程；以便对这几个在卫星移动通信信道传播特性的研究中常用的概率分布函数有更深的理解，对进一步研究卫星移动通信信道传播特性和对信道的建模提供了更为详尽的理论基础； ?对卫星移动通信信道传播特性的研究中常用的信道模型进行了理论上的分析和讨论，并对卫星移动通信信道建模的研究工作提出了一定的看法； ?指出了以前的文献中关于c . loo模型和corazza模型的等同性的证明错误；并从接收信号功率的角度出发，通过理论推导及仿真曲线拟合重新证明了在乡村环境下，这两个模型的确是具有等同性的；从而在对乡村环境下的卫星移动通信信道传播特性进行研究时，可以只采用corazza模型来对实际的信道进行建模，这样可以避免重复的建模工作并提高研究工作的效率和准确性； ?给出了lutz模型在matlab6 . 0 _ simulink4 . 0环境下的软件仿真实现的详细过程和整体仿真测试的对比结果，保证了该模型在硬件实现时的可靠性和可行性，从而可以将它们应用于指导模型的硬件仿真实现并可以降低硬件实现时的风险。 - It's difficult to find corazza in a sentence. 用corazza造句挺难的
