摘要
主要从通信系统设计的角度出发,对超短波通信链路分析进行了初步探索,介绍了能量传播分析法和链路余量分析法以及多径条件下的考虑。结合工程实践,给出了超短波通信链路分析示例,这将有助于系统工程师预知系统设计性能、控制技术风险、进一步提高信道估值的可信度。
An approach to ultrashort wave link is put forward for the communication system design. The article first analyses the energy spread of electric wave ,then introduces a method of link margin,and takes the multi - pathway disturbance into eonsideration. Combining with practice,illustration is provided. All of these are helpful for the system engineer foreseeing the system performance,controlling the risk of technique and improving the reliability of llnk budget.
