In this paper we present a convex optimization problem for solving the
rational covariance extension problem. Given a partial covariance seq
uence and the desired zeros of the modeling filter, the poles are uniq
uely determined from the unique minimum of the corresponding optimizat
ion problem. In this way we obtain an algorithm for solving the covari
ance extension problem, as well as a constructive proof of Georgiou's
seminal existence result and his conjecture, a stronger version of whi
ch we have resolved in [Byrnes et al., IEEE Trans. Automat. Control, A
C-40 (1995), pp. 1841-1857].
