| 摘 要： | 正交匹配追踪算法是一种重要的压缩感知重构算法,针对正交匹配追踪算法中当前信号的最优估计,每一个采样点都有它的局部性质,且相邻采样点之间必然相互影响.本文基于局部性质,对正交匹配追踪算法进行改进,提高了对稀疏参数的估计精度,实现了信号的重构,实验证明了该方法的有效性.

| Abstract: | Orthogonal matching pursuit algorithm is a kind of important compression sensing reconstruction algorithm, in view of the optimal estimation of the current signal in the orthogonal matching pursuit algorithm, each sampling point has its local proper- ty, and the neighboring sampling points influence each other. This paper puts forward improving orthogonal matching pursuit algorithm based on local property , improves the estimation precision of sparse parameter, realize the signal reconstruction, the experi- ment proves the validity of this method. |
