METHOD FOR ENCODING/DECODING SIGNAL AMPLITUDE BY MEANS OF FOLDING AND AUXILIARY INFORMATION LABELS

摘要

The invention relates to the encoding and decoding of a data signal. The encoded signal is obtained on the basis of a multi-level signal with information and using symmetry and folding at limits determined by the physical characteristics of the devices. The technique consists in indicating the limits of the amplitude of the signal, which serve as axes of symmetry, about which the signal is folded as many times as necessary until a signal is obtained that has an amplitude within the defined limits. Auxiliary information labels are added to the transmitted signal in order to indicate the number of folds in each sample of the signal. This information is detected and used by the decoder in the receiver in order to correctly recover the information from the signal.
