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。
With the sustained and rapid development of GSM network data services, spectrum resources are increasingly scarce. In order to alleviate the shortage of spectrum resources, more frequent frequency reuse methods are generally used to improve network capacity. However, for certain spectrum resources, close frequency reuse will also increase interference while enlarging network capacity. The interference and interference location in GSM system and the solution based on frequency reuse technology are studied. Combined with the case of adjacent channel interference in Jiangmen city and the practical working experience, the causes and solutions of interference are respectively analyzed and studied. Can provide reference for network maintenance.
