摘要
智能天线对消除TD-SCDMA系统中用户间相互干扰发挥着重要作用,智能天线具有自适应地跟踪用户信号,消除干扰的技术特点.本文深入研究了智能天线自适应波束形成算法,重点研究了最小均方(LMS)算法和最小二乘法(RLS),实现了智能天线在干扰消除中的设计与仿真,并对仿真结果进行比较分析,证明其在抑制TD-SCDMA系统中干扰的有效性.
The Smart Antenna plays an important role to suppress the interference among users in TD-SCDMA, the smart antenna has the features that it can adaptive track the user signals and suppress the interference. The smart antenna adaptive beam-forming algorithms are researched deeply in the thesis, especially the least mean square（LMS） and least squares（RLS） algorithm, and compare and analyze the result then prove the advantage and disadvantage of two algorithms. The results prove that it can suppress interference in TD-SCDMA system with the effectiveness.
