摘要

LMS算法的另一种形式是将均方误差表示为与滤波器抽头权重单调相关的一组双曲变量的凸函数。通过大量的仿真研究表明，该算法非常适合基于cordic的实现，并且具有很好的收敛特性。

A hyperbolic LMS algorithm for CORDIC based realization

An alternate formulation of the LMS algorithm is presented by expressing the mean square error as a convex function of a set of hyperbolic variables that are monotonically related to the filter tap weights. The proposed algorithm is ideally suited to CORDIC-based realization and possesses very good convergence characteristics as revealed via extensive simulation studies.

期刊介绍： Journal of Signal Processing is an academic journal supervised by China Association for Science and Technology and sponsored by China Institute of Electronics. The journal is an academic journal that reflects the latest research results and technological progress in the field of signal processing and related disciplines. It covers academic papers and review articles on new theories, new ideas, and new technologies in the field of signal processing. The journal aims to provide a platform for academic exchanges for scientific researchers and engineering and technical personnel engaged in basic research and applied research in signal processing, thereby promoting the development of information science and technology. At present, the journal has been included in the three major domestic core journal databases "China Science Citation Database (CSCD), China Science and Technology Core Journals (CSTPCD), Chinese Core Journals Overview" and Coaj. It is also included in many foreign databases such as Scopus, CSA, EBSCO host, INSPEC, JST, etc.
