Linear and quadratic time-frequency signal representations

Franz Hlawatsch, +1 more
- 01 Apr 1992 - 
TL;DR: A tutorial review of both linear and quadratic representations is given, and examples of the application of these representations to typical problems encountered in time-varying signal processing are provided.
Journal ArticleDOI

Kernel design for reduced interference distributions

J. Jeong, +1 more
- 01 Feb 1992 - 
TL;DR: The authors present a class of time-frequency signal representations called the reduced interference distribution (RID), and a systematic procedure to create RID kernels, (or, equivalently, compute RIDs) is proposed.
Journal ArticleDOI

Frequency‐time decomposition of seismic data using wavelet‐based methods

Avijit Chakraborty, +1 more
- 01 Dec 1995 - 
TL;DR: In this paper, the authors proposed a matching pursuit algorithm to map a seismogram into the frequency-time (FT) space of seismic data, and showed that the matching pursuit provides excellent spectral localization, and reflections, direct and surface waves, and artifact energy are clearly identifiable.

Non-parametric techniques for pitch-scale and time-scale modification of speech

Eric Moulines, +1 more
- 01 Feb 1995 - 
TL;DR: This contribution reviews frequency-domain algorithms (phase-vocoder) and time- domain algorithms (Time-Domain Pitch-Synchronous Overlap/Add and the like) in the same framework and presents more recent variations of these schemes.

Time-scale energy distributions: a general class extending wavelet transforms

Olivier Rioul, +1 more
- 01 Jul 1992 - 
TL;DR: The theory of a new general class of signal energy representations depending on time and scale is developed, and specific choices allow recovery of known definitions, and provide a continuous transition from Wigner-Ville to either spectrograms or scalograms (squared modulus of the WT).
