Abstract: Complex Kalman filters are used to process complex signals that appear in various fields of science and engineering. The augmented complex Riccati equation is related to time-invariant augmented or widely linear models. The off-line solution of the Riccati equation is a prerequisite for determining the steady-state augmented complex Kalman filter parameters before any measurements are observed. Iterative per-step and doubling algorithms for the solution of the complex Riccati equation are derived and their computational requirements are derived, leading to the ability to select the fastest iterative algorithm.
