This note summarizes state-space formulae for all key spectral factorizations appearing in the discrete-time H2/Hx optimization. The factorization problems are categorized into three groups. The construction of solutions is formulated into finding special coprime factors of a given transfer matrix by the associated discrete algebraic Riccati equation. Solution procedures for the three groups are in general the same, and under that we may lead to yield a unify approach.
