This work presents an extension of the classical LMS-based Frost algorithm to include both the Normalized LMS (NLMS) and the Binormalized Data-Reusing LMS (BNDR-LMS) algorithms. Two simple versions of these algorithms are derived for the Frost structure. These new algorithms were applied to a DS-CDMA mobile receiver. The results showed a considerable speed up of the convergence rate compared to the LMS Frost.
