摘　　要：本文设计了一种容易实现的新算法.通过快速稀疏度评估的方法处理稀疏度未知的信号,有效地提高了疏密度评估的效率;同时,在重构过程中,避免了迭代时产生的观测向量的投影运行;此外,应用反应信号可能性的系数,验证了设计算法的性能.当稀疏性相对较大时,论文中所设计的算法的性能将明显下降.A new algorithm that is easy to implement is designed in this study.The scheme copes with signals of unknown sparsity by means of fast sparsity estimation.Meanwhile,in the process of reconstruction,the projection operation of observation vector during the iteration and further to reduce the complexity of operation is avoided.In addition,the performance of the design algorithm is verified by applying the coefficient of the signal probability and the performance of the algorithm designed will decline significantly when the sparse is relatively large.
