摘　　要：给出了智能天线技术在系统级研究的理论模型,推导了采用多用户检测和自适应智能天线技术后的容量和负载评估理论模型。基于该模型,给出了一种新的接入控制算法,并为实时多媒体业务提出了一种先进的动态信道分配算法。仿真结果表明,提出的理论模型和无线资源管理算法适用于TD-SCDMA系统,能够显著提高系统性能,用于实际TD-SCDMA网络的规划优化。Due to multiuser detection and smart antenna techniques, the radio resource management schemes for WCDMA and cdma2000 systems could＇t be adopted for TD-SCDMA directly. Based on the theoretical analysis of the smart antenna and multi-user detection impacting on the system＇s capacity, an available capacity and load estimation model were proposed, and an advanced admission control algorithm was presented. Meanwhile, a novel admission control and a dynamical channel allocation （DCA） scheme were proposed. Simulation results show that the proposals are available for TD-SCDMA, which can help network planning and optimization.
