Research abstract
THIS WORK ADDRESSES THE RECOGNITION OF TRANSIENT AND NONSTATIONARY SIGNALS BY A COLLECTION OF FEATURE EXTRACTION ALGORITHMS FOLLOWED BY LOGIC THAT COMBINES THE FEATURE ESTIMATES TO PRODUCE SIGNAL CLASSIFICATION. THE FEATURE EXTRACTION ALGORITHMS INCLUDE ESTIMATORS FOR SPECTRAL COHERENCE, A TECHNIQUE THAT ILLUMINATES THE PRESENCE OF RHYTHMIC MODULATIONS IN SIGNALS. NEURAL NETS WILL BE EXAMINED AS A METHOD FOR ENCODING SIGNAL PROCESSING FEATURES AND FOR PERFORMING THE CLASSIFICATION FUNCTION.
