摘要
小波包可对高频信号进行分解.在区间上连续四重多小波的基础上,给出区间上连续四重多小波包的定义,并分析了区间上连续四重多小波包的性质,进而给出其分解与重构算法.
Wavelet packets can decompose high frequency signals. On the base of the definition of continuous multi - wavelet of multiplicity of 4 on the interval, the paper presents the definition of continuous multi - wavelet packets of multiplicity of 4 on the interval. According to the analyzed properties of continuous multi - wavelet packets of multiplicity of 4 on the interval, the decomposition and reconstruction algorithm for these multi- wavelet packets are given.
