ABSTRACT:
Adaptive equalization system for allowing the equalization of a base-band line of a DCE, includes an adaptive filter for adjusting its coefficients in accordance with an adaptive algorithm. The equalizer includes controls to work during a preliminary period, in an adaptive or non-adaptive mode according to the convergence of the recursive algorithm process. The algorithm is triggered depending on whether the equalized signal belongs to one of several predefined intervals of convergence. After this preliminary period, when the mean square of the residual error is considered small enough to ensure the convergence of the adaptive process, the algorithm is computed on a continuous mode.
