Abstract :
An algorithm for two-dimensional autoregressive moving average (ARMA) and moving average (MA) modeling in the Fourier transform domain that can be implemented in other domains is presented. The algorithm derived here is based on the equationary model (recursive-like structure) which can match, in the least square sense, the unknown system. Simulation examples of two-dimensional system modeling are given to demonstrate the performance of this algorithm
