Abstract :
Convergence properties of the constrained and the unconstrained frequency-domain block LMS algorithms are analyzed. Comparisons based on both a theoretical analysis and computer simulation are given. It is shown that the unconstrained algorithm has a slower convergence rate and smaller stable range of step size than that of the constrained algorithm
