| 摘 要： | 为了研究智能天线系统中发射信号的到达定位问题，给出了一种基于空间平滑技术的算法，对总体最小二乘法——旋转不变技术的信号参数估计算法进行了改进。仿真结果表明，改进算法不仅适用于独立信号源，而且适用于相关信号源，具有计算量小、分辨率高、对信噪比要求低等特点。

| Abstract: | In order to investigate the locating problems of emitted signals arrival in the smart antenna system,a modified algorithm is proposed.On the basis of spatial smoothing techniquet,he method of total least squares-estimating signal parameters via the rotational invariance technique is ameliorated.Simulation results have been given to verify this modified algorithm for both independent and coherent signals.It shows that a good perform-ance of proposed technique is with low computational complexity,high resolut... |
