Method for generating a multimodulation frame and modulator for carrying out said method

摘要

The present invention refers to a method for generating a multi-modulation frame which includes at least a first time interval (1) and a second time interval (2), said first and second time intervals (1, 2) being defined by first and second modulations, respectively. The method is characterised in that it comprises a step-by-step interchange stage, with at least two steps, for changing the coefficients of a modulation filter from a first set of coefficients associated with the first modulation to a second set of coefficients associated with the second modulation. <IMAGE>
