摘　　要：对于3带r重紧支撑双正交多小波系统,给出了一种构造双正交多小波的一般方法.它是由任意一对3带双正交单小波及两组滤波器构造出来的.由于3带双正交尺度函数的任意性和滤波器组的选取具有很大的自由度,使得可构造出大量的3带双正交多小波。For compactly supported biorthogonal multiwavelet system with dilation factor 3 ,this paper present a general method for constructing biorthogonal multiwavelet by using biorthogonaluni-scaling function and the corresponding biorthogonal wavelets.Because the biorthogonal uni-scaling functioncan be free selected,and choosing of filters has free in the whole process of construction,a lot of biorthogonalmultiwavelets can be constructed.
