ANALYSIS AND DESIGN OF PERIODICALLY TIME-VARYING DIGITAL FILTERS
A description of periodically time-varying systems was developed which completely characterizes the relationship between the spectra of the input and output signals of these systems. The description is the bi-frequency ...
RECONSTRUCTION OF SIGNALS FROM PHASE: EFFICIENT ALGORITHMS, SEGMENTATION, AND GENERALIZATIONS
It is well known that the phase of the Fourier transform of a signal contains a significant amount of information about the signal. Under certain circumstances the knowledge of phase is sufficient to recover the original ...
ADAPTIVE NONLINEAR IMAGE RESTORATION BY A MODIFIED KALMAN FILTERING APPROACH
An adaptive nonlinear Kalman-type filter is presented in this dissertation for the restoration of two-dimensional images degraded by general image formation system degradations and additive white noise. A vector difference ...
TIME-FREQUENCY SIGNAL PROCESSING ALGORITHMS: ANALYSIS AND SYNTHESIS USING WIGNER DISTRIBUTIONS
A tutorial review of several mixed time-frequency representations of signals and systems is presented. Emphasis is placed on the background, extensions, inter-relationships, and applications of the Gabor logon, the Short-time ...
