Adaptive equalization system and method for equalizing a signal into a DCE.

摘要

Adaptive equalization system for allowing the equalization of a base-band line of a DCE within a predetermined range, said system including an adaptive equalizer (312) for continuously adapting its coefficients in accordance with a predetermined adaptive algorithm. The equalizer (312) includes means (311) for storing a plurality of sets of initial coefficients for the equalization process corresponding to a plurality of telecommunication lines and means (310) for measuring 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. <IMAGE>
