摘　　要：为了减小GSM系统中小区间的同频和邻频干扰,通常需要进行频率规划。应用遗传算法和地理信息系统设计开发了针对爱立信GSM900和GSM1800系统的频率规划软件。在开发中充分利用了地理信息系统强大的地理化显示和操作功能,并采用了交叉点存储、变异回退以及分割分步降维的方法以提高遗传算法的执行速度。应用实例表明,使用该软件得到的频率规划结果较好。In order to reduce the interferences between different cells in GSM system, frequency planning is usually needed. This paper describes the development process of a frequency planning software using genetic algorithm and Geographic Information System,which is aimed at Ericsson GSM900 and GSM1800 systems. During the development,the powerful geographic display and operation function of GIS is fully utilized,and methods of crossover point storage,mutation rollback and segment and step to reduce the dimensions are used to improve the execution speed of genetic algorithm. The application indicates that the results of the frequency planning by using this software are good.
