| Abstract: | A procedure to design orthogonal multiwavelet based o n wavelet packet was introduced. The explicit expressions for a group of orthogona l multifilter banks of orthogonal multiwavelets were obtained. The relation bet ween discrete multiwavelet transform and wavelet packet decomposition was disclo sed. The orthogonal prefilter was designed. The experimental results showed that our multiwavelet could perform better than wavelet and GHM multiwavelet in gett ing rid of noise. |
