摘要
针对民航地空通信中最主要的同频干扰问题,全面分析了其存在的各种可能情况.同时基于同频道干扰程度的概念,给出了当存在一个同频道干扰时其干扰程度的计算方法和公式,并指出这种方法同样适用于多个干扰同时存在的情况.这对于从技术角度解决民航地空通信的干扰问题有较高的应用价值.
In the light of at the main cochannel interference of the ATC communication system, this paper analyses allround available cases. It gives the methods and equations of the affection of the cochannel interference on the communication system based on the concepts of cochannel interference degree on the condition that only one interference exists. This paper points out that this method can also adapt to the condition that many interferences exist. This study has important value to take radical measures to solve the problem.
