英文摘要 | This paper presents a fractional order modified least square algorithm (FOMLMS), which involves an iteration order switch strategy, A FOMLMS scheme whose iteration order can be extended into alpha is an element of (0, 2) is investigated. The performance of FOMLMS with the iteration order in different interval (0 < alpha < 1 or 1 < alpha < 2) is separately analyzed. It turns out that, both of a larger iteration order (0 < alpha < 2) and iteration step size can always result in a faster response speed and convergence speed. Therefore, in order to obtain a satisfying convergence speed without sacrificing other performance, a hybrid switch law of iteration order is naturally developed. Finally, the validity of this proposed algorithm is illustrated by three numerical examples. (C) 2016 ISA. Published by Elsevier Ltd. All rights reserved. |
