摘　　要：无线资源管理是第三代移动通信系统中的重要组成部分,用于对业务需求、资源分配、系统容量和稳定性进行控制,而TDD CDMA系统特性及其中引入的智能天线技术使得无线资源管理算法需重新建模设计。本文利用OPNET仿真软件对TDD CDMA系统进行了建模,并且对我们提出的几种适用于TDD CDMA系统的新无线资源管理算法进行了仿真,与传统算法获得的仿真结果对比,验证了其性能增益。Radio resource management is an important component of the third generation mobile communication systems, used to control the quality of services, the allocation of radio resource and system capacity and stability. The system characteristics and smart antennas of TDD CDMA, however, make its RRM need to remodedl. This paper does it by OPNET and simulates several our new RRM algorithms for TDD CDMA. The results show these novel algorithms by considering beam load is more suitable to the TDD CDMA system with smart antennas.
