摘　　要：随着GSM网络数据业务持续快速发展,频谱资源日益紧缺。为缓解频谱资源紧张,一般会采用更紧密的频率复用方式来提升网络容量。但是对于一定的频谱资源,紧密的频率复用在扩大网络容量的同时也会增强干扰。研究了GSM系统内干扰、干扰的定位及基于频率复用技术的解决方案,并结合江门市区同邻频干扰案例和实际工作经验,分别对干扰产生的原因及解决办法进行了分析和研究,可为网络维护提供参考。Along with the sustained and rapid development of GMS network data business, the shortage of spectrum resources becomes increasingly serious. In order to mitigate the spectrum resources, the frequency multiplexing technology is usually used to promote network capacity. However, for a certain frequency resource, the much closer frequency reuse would enhance the interference while expand the network capacity. This paper discusses the interference and interference position in GSM system, including its solutions based on frequency multiplexing technique. And also in combination with practical work experience and the cases of adjacent frequency interference in Jiangmen city, this paper analyzes the causes of interference and its solutions, all this could serve as an important reference for network maintenance.
