Abstract
Two approaches to the characterization of suboptimal solutions are given. The first, via Parrot's theorem, gives all solutions. The second uses J-spectral factorizations and gives a particularly simple parametrization of all solutions. Unlike the time-invariant case, however, J-spectral factorizations do not always exist.
