A Toeplitz Decorrelation Method Using the Maximum Eigenvector
Wang Yong-liang · Dianzi xuebao · 2008
A Toeplitz decorrelation method using the eigenvector corresponding to the maximum eigenvalue(simplified as the maximum eigenvector) is proposed for the DOAs estimation of coherent sources.This method uses the largest eigenvector to construct a new Toeplitz matrix to estimate DOAs of coherent sources.Compared with the conventional decorrelation methods,it has better estimation performance,especially at low SNR scenarios,and it can estimate more coherent sources.Theoretical analyses and simulation results both show that the presented method is effective.
