Compressive sampling offers a new paradigm for acquiring signals that are compressible with respect to an orthonormal basis.
Xx offers xx for xx
This paper describes a new iterative recovery algorithm called CoSaMP that delivers(提供) the same guarantees as the best optimization-based approaches.
3．rigorous bounds on computational cost and storage.
extremely efficient 效率极高
Contemplating this ugly inefficiency, one might ask if it is possible instead to acquire compressive samples. 考虑到这种丑陋的低效率，人们可能会问是否有可能获得压缩样本。
Compressive sampling refers to the idea that, for certain types of signals, a small number of nonadaptive samples carries sufficient information to approximate the signal well.
This paper presents and analyzes a novel signal reconstruction algorithm that achieves these desiderata. 本文提出并分析了一种实现这些需求的新型信号重建算法。
As the name suggests, the new method is ultimately based on orthogonal matching pursuit (OMP) 顾名思义，新方法最终基于正交匹配追踪（OMP）
9．Sparse signals are an idealization that we do not encounter in applications, but real signals are quite often compressible, which means that their entries decay rapidly when sorted by magnitude.
These traits are essential for the translation of compressive sampling from theory into practice. 这些特征对于将压缩采样从理论转化为实践至关重要。
