| 摘 要： | 在第三代蜂窝移动通信系统中,随着同时接入系统的用户数目的增加,系统用户间的相互干扰也逐渐增强,这不仅严重影响了CDMA通信系统的性能,也限制了系统容量的提高.分析了影响WCDMA系统容量的一些潜在因素以及干扰余量与小区负荷的关系,并分别在上行链路和下行链路上,对WCDMA小区容量与覆盖范围的关系、小区负荷变化对服务质量(QoS)的影响以及相邻小区对小区容量的影响进行了分析.

| Abstract: | As the number of users in third generation cellular mobile communication systems increased,the interferences among users are increased as well.The interferences not only reduce the performance of CDMA systems,but limit the capacity of the systems as well.Some potential factors that affect the capacity of CDMA systems and the relationships between the interference margin and the load of the systems are analyzed.The relationships between capacity and the coverage of the system,between the loads and the service of quality(QoS) are analyzed as well. |
