Abstract:
This paper explores the potential of several popular equalization techniques and proposes new
approaches to overcome their disadvantages. Such as the conventional least-mean-square (LMS )
algorithm, the recursive least-squares ( RLS ) algorithm, the filtered-X LMS algorithm and their
development. An H2 optimal initialization has been proposed to overcome the slow convergence
problem while keeping the simplicity algorithms. The effectiveness of the methods proposed in
this paper has been verified.
