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 fir st set of coefficients associated with the first modulation to a second set of coefficients associated with the second modulation.
