Haiying Cui · Journal of Beijing Union University · 2008
Mutlivariate wavelets are a powerful tool for multidimension signal processing.Wavelets filters constructed by tensor product or lattice structure have their own features.In application,to improve the effect of filtering,to constructing wavelet filter meeting some special requirements is still needed,Orthogonal wavelet filter banks with linear phase is a very important property in application of wavelets filters.In reference[6],the way of constructing central-symmetric paraunitary matrix(each element is a bivariate polynomial of order one) is given,and on this basis,compactly supported bivariate of orthogonal lowpass filter with linear phase and corresponding wavelet filters are constructed and one example is also given.
