Objective: The action potential conduction velocity (APCV) estimation was explored in this paper. Methods: Based on
a physiological model of sEMG signal, the APCV estimation result was acquired by using the time-delay estimation of cross correlation,
and the re-sampling technique was utilized to improve the estimation performance. Results: The experimental results showed that the
APCV estimation error could be reduced by the re-sampling technique. Conclusion: The APCV estimation performance could be satisfactorily
acquired by the proposed method. |
