摘　　要：以CCIR关于短波传播信道的模型为基础,结合我国环境特点及地理信息,利用Matlab工具和数据库联合编程技术,实现了短波传播路径损耗预测的全程计算机化。给出了预测算法的计算机实现方法与仿真结果,并对仿真结果和影响信道传输特性的几种主要参数做了较为详细的分析、讨论。研究结果可作为短波通信台站最优化设计、通信网络规划及通信部门的决策支持、宏观管理的依据。By the short-wave communication channel model of CCIR and the information about environment and geography, with the Matlab and database language, the computation of loss prediction for short wave propagation aided by computer is accomplished. The results and the parameters which influence channel transmit are analyzed and discussed. The result of research provide the base for optimization design of shortwave communication station, network planning and the decision-making and maeroscopically supervising of communication department.
