Let a=(a1, a2,···, am)∈Cmbe an m-dimensional vector. Then it can beidentified with an m×m circulant matrix. By using the theory of matrix-valuedwavelet analysis (A.T. Walden and A. Serroukh, Wavelet analysis of matrix-valuedtime-series, Proc. R. Soc. Lond. A458(2002),157-179), we discuss the vector-valued multi-resolution analysis. Also, we derive several different designs of finitelength of vector-valued filters. The corresponding scale function and wavelet functionare given. Specially, we deal with the construction of filters on symmetric matrix-valued function space. |
