摘要
对采用智能天线技术的时分-同步码分多址(TD-SCDMA)系统上行链路容量负载进行了分析,给出了基于智能天线技术的CDMA系统上行链路接入控制算法,并研究了切换用户接入控制门限与新用户接入控制门限的理论模型,通过TD-SCDMA动态系统级仿真验证了本文所提出的算法和模型非常高效.
The uplink capacity and load of the smart antenna based time division-synchronous code division multiple access （TD-SCDMA） system were analyzed. The uplink admission control algorithm, considering the impacts of smart antenna technique, was proposed. The relations of admission control threshold between the new users and the handover users were investigated, and their theoretical analysis model was presented simultaneously. The dynamical system level simulation results showed the proposed admission control algorithms＇ performances and the relations between the admission control threshold and the number of new/handover users.
