A Variable Step Size LMS Adaptive Filtering Algorithm

TIAN Bin-peng,ZHANG Cui-fang, YAN Lei(School of Information Science & Technology,Southwestern Jiaotong University, Chengdu Sichuan 610031,China)  
In this paper, a new adaptive filtering algorithm with fast and variable step size is proposed. On the one hand, theoretical analysis shows that in different channels, the proposed algorithm accomplishes faster convergence and smaller MSE than the LMS and LMSISA . On the other hand , three algorithms (LMS, LMSISA and NLMSISA) are adopted to identify two structure (FIR and IIR ), and the computer simulations demonstrate the characteristics of proposed algorithms. The algori thm is suitable for the adaptive filtering in engineering.
