| Abstract: | In this paper, a method to process surface electromyography signal was presented. It based on AR model and BP neural network. First, we created AR model with the original signal that was pretreated and took the coefficient as its eigenvector. Second, a three-layer BP neural network was designed to classify the muscle movement of forearm with AR model coefficient. The experiment indicates this measure can reduce workload and get the relatively good results. |
