摘要

Virtual-ESPRIT 算法（VESPA）是一种使用高阶统计量（四阶积）的到达方向（DOA）估计方法，据说对非高斯信号的 DOA 估计很有意义。作者提出了 SLS-VESPA，即采用 SLS（结构最小二乘法）方法的 VESPA。计算机模拟显示，与传统的 TLS（全最小二乘法）-VESPA 相比，SLS-VESPA 具有更好的特性。

DOA Estimation by Virtual-ESPRIT Algorithm Using Structured Least Squares Method

Virtual-ESPRIT Algorithm (VESPA), which is a direction-of-arrival (DOA) estimation method using higher-order statistics (fourth-order cumulants), is said to be significant for DOAs estimation of non-Gaussian signals. The authors propose SLS-VESPA, which is VESPA with the SLS (Structured Least Squares) method. Computer simulations show improved characteristics of the SLS-VESPA compared to the conventional TLS (Total Least Squares)-VESPA.
