研究了两相邻频段的EVDO系统干扰共存问题,采用准静态快照(snapshot)系统仿真方法研究存在EVDO邻频干扰时EVDO系统相对容量损失问题。从仿真表明,存在EVDO邻频干扰时,系统相对容量损失<1%,两邻频EVDO系统无需额外带宽就可以共存。
The interference of EVDO systems in two adjacent frequency bands is studied. The quasi-static snapshot system simulation method is used to study the relative capacity loss of EVDO systems in the presence of EVDO interference. The simulation shows that when there is EVDO adjacent channel interference, the relative capacity loss of the system is less than 1%, and the two adjacent frequency EVDO systems can coexist without extra bandwidth.
