A Variable Step-Size LMS Adaptive Filtering Algorithm Based on Error Feedback
In order to solve the problem of LMS algorithm, a new variable step-size LMS algorithm is studied.The algorithm is based on the sigmoid function which builds the non-linear functional relationship between step and error.By introducing the error feedback strategy to adjust the parameters adaptively, the algorithm solves the problem of setting parameters in the function.Compared with other algorithms, simulation results show that the algorithm performs perfect at convergence rate and steady-state error with a better applicability.
