Abstract :
The purpose of this paper is to systematically study the asymptotic behavior of a version of fast filtering algorithms in discrete time for complex-valued process, and consequently for that of the Riccati equation of one dimension. It is shown that the trajectories generated by these iterations either escape to infinity in finite time, or converge to a fixed point, or are periodic/dense on the real line. Necessary and sufficient conditions for these dynamical behaviors are given in terms of sign definiteness (on the unit circle) of the corresponding dissipation polynomial
