Aiming at the control of impulse noise

a variable step size VFxBSLMS algorithm based on Volterra series expansion model is proposed.The algorithm effectively solves the influence of impact samples on the stability of the algorithm by adding the error signal preprocessing part and nonlinear compression method.Aiming at the problems of the strong correlation of input signals and the convergence speed of the algorithm

the variable step size algorithm idea is introduced into the nonlinear filtering.Simulation results show that the VFxBSLMS algorithm can achieve better convergence under impulse noise background with different intensity.
