Abstract:Based on the AIC method, the energy method, the Gabor method, the phase method and the threshold method, a comparative study to investigate the most suitable algorithm with the wave front point and the relative error as the criterion is presented in this paper. Moreover, the sine wave pulse with different frequencies to analyze the accuracy of the above mentioned algorithm is adopted in this paper. Finally, the most appropriate algorithm based on the above comparative study results is obtained.
