Superframes were first considered by Balan in the context of signal multiplexing, and by Han and Larson from a purely theoretical point of view. Recently, nonhomogeneous wavelet frames have attracted much attention due to the applicability of the fast algorithms designed for their affine counterparts, and also because they offer more freedom to design wavelet masks. This paper addresses (weak) nonhomogeneous dual wavelet superframes in the setting of Walsh-reducing subspaces of $L^2(\Bbb{R}_+,\Bbb{C}^L)$. The authors present a characterization of nonhomogeneous (weak) dual wavelet superframe pairs in a Walsh-reducing subspace of $L^2(\Bbb{R}_+,\Bbb{C}^L)$. Some examples are also provided.
