| 摘 要： | 提出一种基于新息更新的时变步长LMS算法(TVSLMS).该算法结构简单,时变步长设计新颖,与典型的LMS算法,如著名学者Windrow的LMS算法和Doherty和Porayath所提出的DLMS算法相比,TVSLMS算法收敛速度最高.尤其是算法所引入的收敛加速度,对收敛速度具有灵敏的调速作用.

| Abstract: | A time-varying step LMS algorithm(TVSLMS),based on innovation renew is proposed.The TVSLMS has a simpler algorithm structure and a rational time-varying step.As compared with the mainly typical LMS algorithms like basic LMS and DLMS,it is faster in convergence speed.Furthermore,the convergence accelerator,a totally new parameter,can speed its convergence obviously. |
