Abstract

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.
