Abstract
A new normalized constant modulus algorithm is proposed that has a mor e desirable error performance surface (EPS) than the existing constant modulus blind equalization algorithms. We show that for an autoregres sive channel, a well-known class of undesirable local solutions (ULS's ) does not exist, EPS's and convergence of the parameters are shown fo r a number of channels for which well-known algorithms are known to po ssess ULS's.
