Abstract:
An adaptive equaliser for equalising digital signals with analogue modulation, generated as a result of a premodulation filter (GFIL) said equaliser having means for generating a training sequence formed by a previously known sequence of symbols (TS) and which is applied to the equaliser simultaneously with the reception of the digital signals in order to perform an initial estimation of the coefficients of the filter or filters of the equaliser during a training phase of the operation; said equaliser being characterised in that the means for generating the training sequence employed in its training phase is the result of applying the previously known sequence of symbols (TS) to a filtering means (SHAP) whose transfer function is the same as that of the premodulation filter (GFIL) employed in the modulator associated with the generation of the digital signals with analogue modulation.
