    • Abstract
  • Wavelet analysis is a focus of international research. The result of Mallat algorithm is included in the result of wavelet packet algorithm. Old algorithm of wavelet packet put the results in the order of wavelet packet. It is good for mathematics, but not good enough for engineering. In many applications, we wish the result of algorithm can correspond to simple physics. As an example the Shannon wavelet Packets are discussed in detail, and Wavelet packets algorithm which put result in the order of frequenc...
