Abstract
This paper focuses on the properties of real orthogonal matrices and the applications to the construction of paraunitary multifilter banks. Firstly, formulas of multiple multiplications of real orthogonal matrices as well as some interesting applications are given. Secondly, the above results are applied to give an easy approach to compute a class of paraunitary multifilter banks. In the end, some numerical examples are developed to illustrate the proposed technique.
