| Abstract: | Some algorithms of LMS were discussed and a variable step size parallel LMS algorithms were put forward based on theoretical analysis, which can improve the convergence speed of the LMS algorithms and make it meet the need of high speed data processing. The principle and concrete completing steps of this LMS algorithms were researched. At the same time the algorithms were simulated with the MATLAB by changing characteristic parameter. The advantages of the variable step size parallel LMS algorithms were proved by results. |
