| Abstract: |
| In this paper we study application about the compressed sensing in large-scale signal recovery problem. By the modified HS conjugate gradient method and smoothing technique, the algorithm which possesses better reconstruction effect is obtained. Preliminary numerical results show that our algorithm is suitable for solving large-scale sparse signal recovery problems. |
