摘要 论文提出了一种基于信道冲激响应数据共轭重排的修正高分辨谱估计方法。仿真结果显示,对非相关多径信号,基于未修正和修正的谱估计方法均具有较好的高分辨性能,但修正的算法能正确区分相关多径信号,而未修正的算法却无法分辨。证明了论文提出的方法能应用TD-SCDMA系统多用户多径信号DOA估计,实现对期望用户终端的精确定位。 In the paper, the method based on conjugate CIR data being rearranged is present ed. Computer simulation results indicate that both the unmodified and the modified DOA estimation methods can identify uncorrelated multi-path signals perfectly. However, the modified algorithm can identify the correlated multipath signals perfectly while the un-modified algorithm fails to do so. Computer simulation results verify that the present method can be used in TD-SCDMA System for DOA estimation of Multi-path Signals, t...
