| 摘 要： | TD－SCDMA已经由国际电联（ITU）正式采纳，成为未来第三代移动通信系统（IMT200）的一个重要的部分并由3GPP组织进一步标准化。作为TD－SCDMA系统中关键技术之一的智能天线技术能够使系统在调整运动的信道环境中的达到较好的性能。在本文中，首先介绍了TD－SCDMA系统模型，然后，解释了智能天线技术的基本概念以及在调整运动环境中应用该技术的行性。同时，给出了在不同速度的调整运动环境中的相应的仿真结果。可以看,到在TD－SCDMA系统中使用智能天线技术可以获得很的系统性能并能够满足第三代移动通信系统的各种需求。

| Abstract: | TD-SCDMA(Time Division Synchronous Code division Multiple Access)has been accepted by the ITU (International Telecommunication Union) as a 3G standard. and is being standardized in 3GPP (Third Generation Partnership Project)1]. Smart .antennas as one of the. key technologies used in the TD-SCDMA can provide. good system performance with high mobile velocity In this paper, the system model of TD-SCDMA is introduced at first Then the concept of smart antennas and its feasibility under high vehicle channal ere described. Simulation results in the uplink with different high speeds are also included in this paper It can been seen that smart antennas used in TD-SCDMA will get good performance and meet the requlrements of the 3rd generation moblie. systems. |
