【Abstract】 In order to recover the original signal quickly and accurately, a new modified conjugate gradient method is proposed by using the compressed sensing theory, and the global convergence and sufficient descent of the method are proved. Finally, numerical experiments show that the original signal can be recovered quickly, indicating that the algorithm is effective.更多还原
