Abstract
This paper proposes a new representation for the predictor estimates recursion andcorresponding Riccati equation for discrete-time,time-variant descriptor systems. The introduced "9-block" form for the predictor and Riccati equationpresents an interesting simple and symmetric structure, which enable us to treat directly the most general systems where state and measurement noises are correlated.
