Abstract :
Combination approaches provide an interesting way to improve adaptive filter performance. In this paper, we use one of such approaches known as dasiaconvex combination of two transversal filterspsila for speech enhancement. In addition, both fixed and variable step size cases are examined. As our simulation results show, the variable step size version of the algorithm outperforms the other case in a sense of convergence rate and steady-state error.
