New variable step-size LMS algorithm and its simulations

Meng Lingling Qin Xiujuan(College of Information Science and Engineering,Yanshan University,Qinhuangdao 066004)  
The conventional fixed step size LMS algorithm is difficult to exquisite the fast convergence speed and low steady state error.On the basis of the problem,a new LMS a lgorithm of variable step size is proposed based on a brief discussion on standard LMS.The new algorithm has higher speed of convergence than the standard LMS algorithm.The performance of this paper algorithm is better than that of standard LMS with the theoretical analysis and computer simulations,especially in low SNR situation.The new algorithm is much better when applied to echo elimination.
