摘　　要：本文提出了GHM类正交多小波滤波器组的完备的因子化形式和参数化方法,可用于这类多小波的优化设计和有效实现,同时给出了时频最优准则下的设计实例。*A factorization formula and its corresponding parameterization method of the GHM-like orthogonal multiwavelet filter bank are proposed in this paper, which can be applied to the optimal design and efficient implementation of this kind of multiwavelets. A design example of the multiwav- elets with optimum time-frequency resolution is given.
