In this paper, we presents an improved OMP algorithm. Then the sparse reconstruction problem of OMP algorithm under the influence of the noise is studied. The conditions of SNR parameters for sparse reconstruction are obtained. Finnally, numerical simulation is used to verify the above conclusions.
