  • Abstract
    The derivation of the Cramer-Rao bound (CRB) in [ldquoPerformance Analysis of the FastICA Algorithm and Cramer-Rao Bounds for Linear Independent Component Analysis,rdquo IEEE Trans. Signal Process., vol. 54, no. 4, Apr. 2006, pp. 1189-1203] contains errors, which influence the matrix form of the CRB but not the CRB on variance of relevant off-diagonal elements of the demixing matrix. In this correspondence, we correct these errors.
