摘要 为了实现基于TD-SCDMA智能天线圆-角定位,针对我国TD-SCDMA采用的是非Vandermonde结构的8阵元均匀圆阵智能天线,不能直接采用MUSIC算法对移动台的来波方向(DOA)进行估计的特点,对基于TD-SCDMA智能天线进行了预处理,使MUSIC算法能够用于基于TD-SCDMA智能天线的DOA估计,同时考虑到实际应用分别对理想智能天线和非理想智能天线的MUSIC算法的性能进行了分析。 For circle-angle location of signal source based on smart antenna of TD-SCDMA, Considering that the smart antenna of TD-SCDMA is 8 elements of uniform circular array(UCA), of which array manifold is not Vandermonde, then MUSIC algorithm can't direct be used to estimate direction of angle(DOA).The smart antenna of TD-SCDMA is preprocessed so that MUSIC algorithm can be used to the estimation of DOA based on TD-SCDMA, and its performance is analyzed in the paper.
