Two-channel variable-step-size forward-and-backward adaptive algorithms for acoustic noise reduction and speech enhancement
We propose two new two-channel variable-step-sizes forward and backward algorithms These two new algorithms improve their previous fixed-step-sizes based LMS algorithm. The convergence speed and the steady-state values characteristics are improved. These new proposed algorithms have shown a very important improvement in the steady-state and in the mean-square-error values (convergence speed).
