基于子空间迭代的快速高分辨技术

A Fast High Resolution Technique Based on the Subspace lteration

本文应用子空间迭代技术于多源定位问题中，可以快速得到信号或噪声子空间，而无需对原协方差矩阵做特征分解。理论分析与计算机模拟表明：该方法性能与Ｍｕｓｉｃ相近，然而计算量却大大减小。

In this paper.we present a subspace iteration method which can fast obtain the signal or noisesubepace without eigendecomposition.Theoretical analyses and computer simulations verify that the performance of this method is similar to that of music meth<xl,but the reduction in computational complexity is substantial.
