| 摘 要： | 证明了现有TD-SCDMA智能天线系统的发信部分只能用于基带波形的预均衡,根本不具备信号来波方向(DOA)检测、波束形成、空分多址这些智能天线系统应具备的基本功能,将形成一个上行容量大于下行容量的特殊系统,不能达到3G移动通信系统的基本要求.给出一种在TD-SCDMA系统中实现DOA检测,波束形成的基本方法,可以起到空分多址的作用.若使用该技术改造现有的TD-SCDMA系统,可以大幅度提高TD-SCDMA系统的性价比.

| Abstract: | This paper has proved that the existing TD-SCDMA smart antenna system can be used only for baseband waveform pre-equalization,with no basic functions needed for smart antenna system at all such as DOA(direction of atenna) detection,beamforming,and space division multiple access.It will lead to a special system whose uplink capacity is larger than the downlink one.Unable to meet the basic requirements of 3G mobile communication system.This paper proposes a basic method which can realize the DOA detection and beamforming in the TD-SCDMA syetem to provide the capability of space division multiple access.The ratio of performance over cost of TD-SCDMA system can be greatly improved |
