Abstract: |
The comparison of several definitions of CWT indicates that Haar wavelet and Mexico wavelet are base wavelet.Then one method of constructing base wavelet based on convolution is put forward.It is proved that wavelets produced by scale functions are base wavelet. |
Key words: wavelet base wavelet scale function MRA |
