1. A method for detecting and classifying signals, comprising:

  • acquiring a data signal from a dynamical system;

    pre-processing the data signal;

    estimating the preprocessed signal'"'"'s derivative to generate a derivative vector;

    applying an expansion function to the derivative vector to generate estimated coefficients; and

    processing the estimated coefficients to classify the data signal.
