Comparison of performance (NMSE versus SNR) between the original Bofill and Zibulevsky’s method based on the ℓ 1 -criterion of Equation ( 4 ) (L1 Minimization), the modified ℓ 1 -criterion of Equation ( 14 ) after multisource selection when: the noise standard deviation is known (Oracle Modified L1 Minimization) or estimated via either the DATE (Modified L1 Minimization) or the MAD (MAD Modified L1 Minimization).
