Deterministic selection of pilot tones for compressive estimation of MIMO-OFDM channels
2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015This paper addresses the problem of channel estimation in multiple-input and multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems for the case when the underlying multipath channel is approximately sparse in the angle-delay domain.

The ISO/CCITT standard for continuous-tone image compression
IEEE Global Telecommunications Conference, 1989, and Exhibition. 'Communications Technology for the 1990s and Beyond, 2003The ISO/CCITT Joint Photographic Experts Group is in the process of developing an international standard for general-purpose, continuous-tone still-image compression. A brief history is presented as background to a summary of the past year's progress, which was highlighted by definition of the overall structure of the proposed standard.

Efferent-induced change in human cochlear compression and its influence on masking of tones
Neuroscience Letters, 2010Several lines of evidence suggest that medial olivocochlear (MOC) efferent neurons modify cochlear output to improve signal detection in noise. In animal models, stimulation of MOC efferents reduces the amount of compression in basilar membrane (BM) growth functions.

The weaker of two temporally overlapping complex tones can be easier to hear when the tones are asynchronous than when they are synchronous. This study explored how the use of fast and slow five-channel amplitude compression, as might be used in hearing aids, affected the ability to use onset and offset asynchronies to detect one (signal) complex tone ...

A lossless 2-D image compression technique for synthetic discrete-tone images
Proceedings DCC '98 Data Compression Conference (Cat. No.98TB100225), 2002A new image compression technique, flexible automatic block decomposition (FABD), losslessly compresses typical discrete-tone pseudo-color images 1.5 to 5.5 times more compactly than GIF, and up to twice as compactly as JBIG. The algorithm is designed to exploit the two-dimensional redundancy in an image by expressing the image in terms of itself ...

Lossless compression of continuous-tone images (HP)
2000Lossless compression of images is an important research field, nowadays. In this paper, we survey some of the recent advances in lossless compression of continuous-tone images. The modeling paradigms underlying the state-of-the-art algorithms, and the principles guiding their design, are discussed in a unified manner.

The effect of elastic compression on the venous tone in patients with varicose veins.
VASA. Zeitschrift fur Gefasskrankheiten, 1992The long term effect of elastic compression, with an emphasis on the changes in venous wall elasticity, was studied in 10 limbs with varicose veins. By simultaneously measuring venous volume, using the air plethysmograph (APG), and venous pressure, while the venous outflow was occluded, the pressure/volume (P/V) relationship of the venous system of the
