【Abstract】 We study the compressive sensing with noise.We propose a new strategy for compressive sensing based on SCAD,and we give an efficient thresholding algorithm for solving the new model.The new method is robust to the observation noise. These fundamental properties of the compressive sensing strategy based on SCAD are supported and demonstrated both by simulations and theoretical results.更多还原
