摘要： An adaptive equalization system for allowing the equalization of a base-band line of a DCE within a predetermined range, includes an adaptive equalizer for continuously adapting its coefficients in accordance with a predetermined adaptive algorithm. The equalizer includes storage for a plurality of sets of initial coefficients for the equalization process corresponding to a plurality of telecommunication line characteristics and circuits for estimating the energy of the received signal. From the estimation of the energy of the signal on the line, there is derived one set among the plurality of sets of initial coefficients which are then used for setting the equalization before initiating the convergence process. An efficient and very simple equalization process is therefore provided which is ensured to converge whatever the characteristics of the line within the considered range.
