| Abstract: | Adaptive filtering is widely used in many fields such as signal detecting, signal recovering and digital communication, so it is an important research title in academia. A new modified variable-step LMS algorithm is presented. The step size decreases according to the convergence extent. It is shown, according to the result, that the adaptive filter designed based on this algorithm has the advantages of easier operation and faster convergence. |
