Variable step-size LMS algorithm based on modified arctangent function

GUAN Sihai;LI Zhi;School of Electro-Mechanical Engineering,Xidian University;  
In order to balance the computational time,steady-state error,convergence rate,tracking performance and anti-noise performance,a new variable step-size LMS algorithm is proposed.It is a solution to solve the problem of poor performance under low SNR and many artificial parameters,exploiting the arctangent function,and dynamically adjusts step-size based on the error correlation function.The theoretical analysis are conducted,including the complexity of the algorithm,the steady state misadjustment,convergence rate and tracking performance and anti-noise performance,and design experimental simulation comparison under the condition of the high signal-to-noise ratio and low signal-to-noise ratio.The theoretical analysis and simulation results show that this algorithm can achieve better convergence rate,tracking speed,lower steady state error and misadjustment under high and low SNR conditions.
