从一个系统实例看衰落概率对总体设计的影响

在2～10GHZ频段,视距微波信道衰落是不可避免的。本文通过对一个实际通信系统进行总体参数估算,分析说明微波视距传输信道的衰落和衰落概率对系统总体设计的影响。指出加强对微波传输衰落的研究,对于经济合理地进行系统设计、发展我国高速率的数字通信是至关重要的。

A View of Fading Probabilities Effects on Radio System Design from a System Example

At the frequency bands between 2GHZ and 10GH Z, channel fading of line-of-sight microwave links is not avoid. This paper analyses transmission fading and fading probabilities have an effects on system design by parameter evaluation of a practice communication system. It is very essential to make emphatically a study of chanel fading so as to design reasonably radio systems and develop high capacity digital radio relay systems.
