Exact Sparse Signal Recovery via Orthogonal Matching Pursuit with Prior Information
Jinming Wen, Wei Yu
The orthogonal matching pursuit (OMP) algorithm is a commonly used algorithm for recovering -sparse signals $\x\in \mathbb{R}^{n}$ from linear model $\y=\A\x$, where $\A\in \mat…

A Modified KZ Reduction Algorithm
Jinming Wen, Xiao-Wen Chang
The Korkine-Zolotareff (KZ) reduction has been used in communications and cryptography. In this paper, we modify a very recent KZ reduction algorithm proposed by Zhang et al., resu…
