快速Cadzow算法和一个梯度变量
Fast Cadzow's Algorithm and a Gradient Variant
摘要：
Cadzow算法是一种针对低秩Hankel矩阵信号的去噪和恢复方法。在本文中，我们首先介绍了一个快速Cadzow的算法，它是通过将一个新的子空间投影，以减少在Cadzow的算法中的SVD的高计算成本。针对Cadzow算法和快速Cadzow算法在信号去噪时均方误差不减的问题，提出了梯度法和快速梯度法。大量的实验性能比较表明，所提出的算法可以更有效地完成去噪和恢复任务。
英文摘要：
The Cadzow's algorithm is a signal denoising and recovery method which was designed for signals corresponding to low rank Hankel matrices. In this paper we first introduce a Fast Cadzow's algorithm which is developed by incorporating a novel subspace projection to reduce the high computational cost of the SVD in the Cadzow's algorithm. Then a Gradient method and a Fast Gradient method are proposed to address the non-decreasing MSE issue when applying the Cadzow's or Fast Cadzow's algorithm for signal denoising. Extensive empirical performance comparisons demonstrate that the proposed algorithms can complete the denoising and recovery tasks more efficiently and effectively.
