Abstract :
An alternate formulation of the LMS algorithm is presented by expressing the mean square error as a convex function of a set of hyperbolic variables that are monotonically related to the filter tap weights. The proposed algorithm is ideally suited to CORDIC-based realization and possesses very good convergence characteristics as revealed via extensive simulation studies
