Abstract :
A constructive factorization procedure for a polynomial paraunitary matrix as a product of atomic paraunitary matrices, each of lowest degree, is given. The generic form of these paraunitary factors results from the use of projection matrices. In the univariate case, each factor is of degree 1. In the multivariate case, the generic factor is constructed based on the assumption of its existence.
