Wavelet-based data compression of power system disturbances using the minimum description length criterion

Minimum Description Length Criterion

he intelligibility of speech in communication systems is generally reduced by interfering noise. This interference, which can take the form of environmental noise, reverberation, competing speech, or electronic channel noise, reduces intelligibility by masking the signal of interest. The reduction in intelligibility is particularly troublesome for listeners with hearing impairments, who have gr...

Translation-invariant denoising using the minimum description length criterion

A translation-invariant denoising method based on the minimum description length (MDL) criterion and treestructured best-basis algorithms is presented. A collection of signal models is generated using an extended library of orthonormal wavelet-packet bases, and an additive cost function, approximately representing the MDL principle, is derived. We show that the minimum description length of the...

A Minimum Description Length Proposal for Lossy Data Compression

We give a development of the theory of lossy data compression from the point of view of statistics. This is partly motivated by the enormous success of the statistical approach in lossless compression, in particular Rissanen’s celebrated Minimum Description Length (MDL) principle. A precise characterization of the fundamental limits of compression performance is given, for arbitrary data source...

Simultaneous Noise Suppression and Signal Compression using a Library of Orthonormal Bases and the Minimum Description Length Criterion

We describe an algorithm to estimate a discrete signal from its noisy observation, using a library of orthonormal bases (consisting of various wavelets, wavelet packets, and local trigonometric bases) and the information-theoretic criterion called minimum description length (MDL). The key to eeective random noise suppression is that the signal component in the data may be represented eeciently ...
