信号处理和采集中的密集增长方法，即压缩感知方法，允许从少量随机获取的信号系数中恢复稀疏信号。本文分析了几种常用的基于阈值的稀疏信号重建算法。信号满足压缩传感理论所要求的条件。观察了正交匹配追踪、迭代硬阈值化和单次迭代重建算法。实验部分从重构误差和执行时间两方面进行了比较。

英文摘要：
Intensively growing approach in signal processing and acquisition, the Compressive Sensing approach, allows sparse signals to be recovered from small number of randomly acquired signal coefficients. This paper analyses some of the commonly used threshold-based algorithms for sparse signal reconstruction. Signals satisfy the conditions required by the Compressive Sensing theory. The Orthogonal Matching Pursuit, Iterative Hard Thresholding and Single Iteration Reconstruction algorithms are observed. Comparison in terms of reconstruction error and execution time is performed within the experimental part of the paper.
