METHOD AND DEVICE FOR DEMODULATING A CARRIER SIGNAL BY SUBDIVISION OF A BASIC MODULATION INTERVAL IN SEVERAL INTEGRATION SEGMENTS

摘要

THE INVENTION RELATES TO A METHOD AND DEVICE FOR DEMODULATING A CARRIER SIGNAL MODULATED BY DIGITAL DATA WHICH MODIFY ITS CHARACTERISTICS DURING EACH BASIC MODULATION INTERVAL. /P P THE CHARACTERISTICS OF THE CARRIER SIGNAL IS CONVERTED INTO A CONTINUOUS SIGNAL, AND EACH BASIC MODULATION INTERVAL IS DIVIDED INTO N SEGMENTS. THE CONTINUOUS SIGNAL IS INTEGRATED DURING EACH OF THESE SEGMENTS AND THE INTEGRATED CONTINUOUS SIGNAL OBTAINED AT THE END OF EACH SEGMENT IS ADDED WITH THE INTEGRATED CONTINUOUS SIGNALS OBTAINED AT THE END OF THE PREVIOUS N-1 SEGMENTS. /P P THE INVENTION APPLIES IN PARTICULAR TO THE TRANSMISSION OF DATA ON ELECTRIC POWER TRANSMISSION NETWORKS.
