压缩感知信号重建的正交匹配追赶算法（omp），与bp算法相比较有叫高的精度，但是付出了计算量的代价-Compressed sensing signal reconstruction algorithm Orthogonal matching catch (omp), compared with the bp algorithm are called high precision, but at a cost of computation

压缩感知信号重构的算法，用于学习，先稀疏，再观测系数，最后重建- compression algorithm used to study and review, thin, and observation of the reconstruction and
