This paper presents a novel approach for constructing symmetric compactly supported biorthogonal multiwavelets with short sequences. Starting from the symmetric properties of scaling and wavelet functions, parameterized symmetric forms of the polyphase matrices can be derived, which greatly simplify the construction problem of compactly supported biorthogonal multiwavelets. Moreover, according to...
Polyphase matrix extension of scaling vectors is a fundamental approach for the construction of compactly supported biorthogonal multiwavelets, but at the expense of high computations. In this paper, a novel approach through factorization of the unimodular matrix over the Laurent polynomial ring is developed so that closed-form solution can be obtained for the construction of compactly supported biorthogonal...
Polyphase matrix extension of the scaling vector functions plays an important role in the construction of compactly supported biorthogonal multiwavelets. However, the involved computations are rather complex, and there is no unified, direct formula available so far. In this paper, by studying the canonical forms and the product preserving transformations of the polyphase matrices, an abstract algebraic...
