Abstract :
The spectral and inner-outer factorization problems are solved for discrete-time systems with transfer matrices of arbitrary rank. Simple and explicit state-space formulas expressed in terms of the stabilizing solution to the discrete-time algebraic Riccati system are derived. The results are numerically effective since a reliable algorithm for computing such a stabilizing solution is available.
