The paper discusses the factorization of polyphase matrices corresponding to symmetric compactly supported biorthogonal multiwavelets into symmetric lifting factors. This factorization allows parameterization of symmetric compact supported biorthogonal multiwavelets, which can be used in conjunction with numerical optimization to construct symmetric compactly supported biorthogonal multiwavelets with prescribed properties.
