摘要

为了有效地设计移动卫星通信系统，有必要定量地了解多径信号衰落等信道特性。这种特性可以通过接收信号包络的统计分布来研究。提出了一种估计11ghz移动信号路径损耗的多项式模型。此外，还研究了接收信号功率的概率密度函数(PDF)在不同参数下的变异性。路径损耗的多项式模型与实测数据吻合较好。对信道特性的研究估计了信道在各种统计参数下的PDF值，这对移动系统设计人员有直接的帮助。

Channel characterization of mobile signal at 11 GHz

For effective mobile satellite communications system design, it is necessary to know quantitatively the channel characteristics such as signal fading due to multipath. Such characteristics can be studied by the statistical distribution of the received signal envelope. A polynomial model is proposed to estimate the path loss of the mobile signals at 11 GHz. Also, variability of the probability density function (PDF) of the received signal power on various parameters has been investigated. The polynomial model for path loss agrees well with the measured data. The investigations on the channel characterization estimate the PDF of the channel for a variety of statistical parameters, which are directly useful for mobile system designers.
