Resumo: In this work we propose the use of an ARMA equalizer structured on generalized orthonormal bases for communication purposes. This equalizer structure presents a tapped line of all-pass and Iow-pass filters. Such a structure is inherently stable since all its poles are within the unit circle. We also discuss a method for bases parameterizing (poles choice) based on the channel characteristics. The proposed structure performances are compared with conventional FTR equalizer ones. The results are evaluated in terms of MSE and overall numerical complexity. Traditional trained algorithms are employed for filter weight adapting. Our simulations show that the proposed structure leads to enhanced performances offering an alternative reduced complexity solution for communication channel equalization problem.
