Abstract

An optimum basis function is quite necessary for achieving a more effective signal processing of remote blasting vibration wave in wavelet packet transform. To screen this optimum wavelet packet basis from varying wavelet families, signal reconstruction capability of each basis is firstly verified by root mean square error. Different with the conventional approach, retaining capability of signal identifying character is compared secondly by the correlation of initial signal and its compressed body based upon the same energy representation. Findings finally indicate that sym5 is the optimum wavelet packet basis function for such noisy blast signal.
