Variable Tap-Length Adaptive Algorithm Which Exploits both Second and Fourth Order Statistics

摘要：

A new variable tap-length adaptive algorithm which exploits both second and fourth order statistics is proposed in this paper.In this algorithm,the tap-length of the adaptive filter is varying rather than fixed,and controlled by fourth order statistics,whereas the coef-ficient update retains a conventional least mean square (LMS) form.As will be seen in the simulation results,the proposed algorithm has a faster convergence rate as compared with an existing variable tap-length LMS algorithm which is based only on second order statistics in sub-Gaussian noise environments.
