在众多的高分辨谱估计算法中,TLS－ESPAIT算法以估计精度高、分辨率高和运算量较低而深受欢迎.该文提出一种TLS-ESPRIT算法的快速方法,能够进一步降低运算量.“,”TLS-ESPRIT is more important than other high resolution algorithms because it has higher spec trum estimation qaulity and less computation. This paper presents a new method to fasten the TLS-ESPRIT algorithm and decrease the cost of computation.
