DETECTION AND ESTIMATION OF SOLITON SIGNALS - Acoustics, Speech, and Signal Processing, 1996. ICASSP-96. Conference Proceedings., 1996 IEEE Inte

Soliton solutions to nonlinear wave equations have been recently proposed as signaling waveforms in a variety of communication contexts. One such system modulates the relative positions or amplitudes of multiple solitons generated by a nonlinear ladder circuit. At the receiver, there are inherent difficulties in the problems of parameter estimation and detection of soliton signals due to the no...

Signal processing and communication with solitons

Traditional signal processing algorithms rely heavily on models that are inherently linear. Such models are attractive both for their mathematical tractability and their applicability to the rich class of signals that can be represented with Fourier methods. Nonlinear systems that support soliton solutions share many of the properties that make linear systems attractive from an engineering stan...

Coherent signal-subspace processing for the detection and estimation of angles of arrival of multiple wide-band sources

Nonlinear estimation of DEGG signals with applications to speech pitch detection

Speech pitch detection remains a fundamental problem due to importance in numerous aspects of speech processing. Current pitch detectors focus on determining the Glottal Closure Instant (GCI). Accurate GCI measures can be obtained from the Di erentiated Electroglottograph (DEGG) signal. Unfortunately, DEGG signals are not available in most practical applications. A novel method of pitch detecti...
