2-D ADAPTIVE STATE-SPACE FILTERS BASED ON THE FORNASINI-MARCHESINI 2ND MODEL

Based on the Fornasini-Marchesini second model, a technique is develop ed for implementing two-dimensional (2-D) adaptive state-space Biters. First, the relationship between the coefficient sensitivities and the intermediate transfer functions is investigated for the Fornasini-Mar ehesini second model, A least mean square (LMS) adaptive algorithm is then presented by using new systems that generate the gradient signals , Finally, a 2-D adaptive fine enhancer is constructed by using the 2- D adaptive state-space filter to illustrate the utility of the propose d technique.
