چکیده
|
We consider the recovery of high-dimensional sparse signals via ℓ 1 -minimization under mutual incoherence condition,which is shown to be sufficient for sparse signals recovery in the noiseless and noise cases. we study both ℓ 1 -minimization under the ℓ 2 constraint and the dantzig selector. using the two ℓ 1 -minimization methods and a technical inequality,some results are obtained. they improve the results of the error bounds in the literature and are extended to the general case of reconstructing an arbitrary signal. © 2013 shiqing wang and limin su.
