For the contradiction that the variable step size LMS filtering algorithm can not satisfy the higher convergence speed and the lower steady-state error at the same time, the feedback-based algorithm is proposed. This idea is based on the original algorithm, introducing the mathematical relationship of feedback parameters. Then, each parameter of the improved algorithm is simulated and analyzed to obtain the optimal parameter value. Simulation results show that the performance of the improved algorithm is greatly improved. In the filtering process of the echo signal, the filter characteristics of the improved algorithm, ie the ability of error suppression, are multiplied, and the filtering effect is very good.
