| Abstract: | After analysis, the decomposition and reconstruction algorithms in matrix form for the digital signals of finite length under orthogonal and compactly supported wavelet transformation are obtained. Theory and practice verify that there isn't any distortion at the boundary, and the original signals are perfectly reconstructed. |
| Keywords: | wavelet orthogonal and compactly supported wavelet transformation perfect reconstruction |
