An efficient normalized LMS algorithm

open access: yesNonlinear dynamics, 2022
The task of adaptive estimation in the presence of random and highly nonlinear environment such as wireless channel estimation and identification of non-stationary system etc. has been always challenging. The least mean square (LMS) algorithm is the most

A Variable Step-Size Unconstrained Adaptive FD-LMS Algorithm for MDM Transmission

open access: yesIEEE Photonics Journal, 2018
Mode-division multiplexing (MDM) over few-mode fibers has been proposed to break through the Shannon limit of the single-mode fiber. Mode coupling and differential mode group delay are two major drawbacks, which limit the performance of the system.

General block lms algorithm [PDF]

open access: yes2009 35th Annual Conference of IEEE Industrial Electronics, 2009
In this paper, we analyze the conventional block-least-mean-square (BLMS) algorithm. Usual constraints such as real input data, steady-state analysis and positive adaptive step-size parameter are discarded. Some modifications are introduced in order that the new complex frequency-domain BLMS algorithm equals the former versions in case any of the ...
