METHOD AND APPARATUS FOR ENCODING AND DECODING SIGNALS WITH STRUCTURES

摘要

Methods are provided to decompose signals into elementary components that are extracted from a dictionary of waveforms. In a disclosed embodiment, a method is provided to build a structure book with a non-linear iterative procedure, and reconstruct a signal from a structure book. The method is comprised of the steps of reading in a signal (52); choosing a dictionary type (54); reading in the dictionary and building the data structure of correlation coefficients between the signal and the dictionary waveform (56); selecting the waveform of the dictionary from the correlation coefficients (58); subtracting selected waveforms from the signal and update the correlation coefficients data structure (60); testing the structure book precision (62); processing the structure book (64), and reconstructing a signal from the structure book (66).
