Abstract We show that the convergence rate of ℓ 1 {ell^{1}} -regularization for linear ill-posed equations is always ? ( δ ) {{mathcal{O}}(delta)} if the exact solution is sparse and if the considered operator is injective and weak*-to-weak continuous. Under the same assumptions convergence rates in case of non-sparse solutions are proven. The results base on the fact that certain source-type conditions used in the literature for proving convergence rates are automatically satisfied.
