Abstract This paper provides the Cramer-Rao lower bound of alternating separation algorithm. In the Cramer-Rao bound, the “” inversion of a definite matrix must be established, which extends the theory of Cramer-Rao bound. In additional, this Cramer-Rao bound displays the multiple signal effect in the parameter estimated process. By discussion the Cramer-Rao lower bound of Alternating Separation algorithm, some properties of the signal separation operator matrix are given.
