Extension of Multiresolution Analysis and the Construction of Orthogonal Multiwavelets

A procedure of the extension of orthogonal multiresolution analysis is introduced by assuming that $\phi_1(x)$ ia an orthogonal uniscaling function and constructing a new orthogonal multiscaling function $\Phi(x)=\linebreak {} [\phi_1(x),\phi_{2}(x)]^T$\!. Moreover, an explicit formula of the orthogonal multiwavelets associated with $\Phi(x)$ is obtained. Finally, a construction example is given.
