| Abstract: | In this work, we present five new versions of the Fast Newton Transversal Filter algorithm FNTF. The first algorithm is based on a simple modification of the filtering part, by introducing a scalar accelerator parameter. The second algorithm is based on the use of block filtering technique to actualize the local filter coefficients. The third one is a modification of the second by the use of the final filtering errors to actualize the filters coefficients. The fourth and the fifth ones are based, respectively, on the combination of features from the first and the second version. These five new algorithms were proposed to improve the convergence speed of the original version of the Newton algorithm for the identification of the acoustic impulse response and to improve, also, their tracking ability when these systems vary in time. The different algorithms and their comparative results are presented. | ||
