New Classes of LMS and LMF Adaptive Algorithms

In this paper, some adaptive algorithms based on the Least Mean Square (LMS) and Least Mean Fourth (LMF) are proposed. The same approach as the Variable Step-Size LMS (VSLMS), Sign LMS (S-LMS) and Normalized LMF (XE- NLMF) algorithms is used. The convergence speed of these algorithms are compared to that of previous algorithms . It is shown that among the proposed algorithms Variable Step-size XE-NLMF (VS-XE-NLMF) and VSLMS+F have better convergence behavior than that of the previous algorithms.
