摘要
借助于多相位分解,提出了多通道低通滤波器经相位分解后相应的向量的酉扩充方法,由此得到多通道正交小波滤波器所对应的扩充矩阵.这使得与多通道正交小波滤波器相关的矩阵扩充的通解问题得到了系统的解决.
A unitary matrix extension method of the corresponding vectors, obtained from multiple channel low-pass filters by polyphase factorization, is proposed. The extended matrix corresponding to multiple channel orthonormal wavelet filters is also obtained in this paper, which solves the problem of the general solutions of matrix extension associated with multiple channel orthonormal wavelet filters systematically.
