PRISM: a "reversed" multimedia coding paradigm

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
In this work, we present PRISM (power-efficient, robust, high-compression, syndrome-based multimedia coding), a video coding paradigm based on the principles of coding with side information (which, unlike the classical Wyner-Ziv coding scenario Wyner, A et al.

Reverse Concatenation of Product and Modulation Codes

2008 IEEE International Conference on Communications, 2008
Reverse concatenation (RC) architectures, which recently have been deployed in hard-disk-drive (HDD) products, offer crucial advantages in coding such as (i) avoiding error propagation through the modulation decoder, (ii) allowing the use of efficient high-rate modulation codes, and (iii) passing of soft information from the detector to the decoder ...

Fast reversible coding and indexing of colorations

Computing, 1976
Given a non-branched tree withn vertices. Then, by ann-g-coloration we understand a partition of the set of vertices into no more thang classes, such that adjacent vertices belong to different classes. Supposed the set\(\mathfrak{S}\) of alln-g-colorations (for givenn andg) is lexicographically ordered, here are given two algorithms: the first directly

On constructing the Huffman-code-based reversible variable-length codes

IEEE Transactions on Communications, 2001
In this letter, we propose a generic and efficient algorithm that can construct both asymmetrical and symmetrical reversible variable-length codes (RVLCs). Starting from a given Huffman code, the construction is based on two developed codeword selection mechanisms, for the symmetrical case and the asymmetrical case, respectively; it is shown that the ...

Reverse Engineering of Microprocessor Program Code

2012
This paper has an experimental character. Theoretical backgrounds presented here allow creating a research method. The research focus on analysis of microprocessor voltage supply changes. Such analysis based on the presented research assumptions allowed for a rather high efficiency of decoding program without interference in the internal structure of ...

A reversible code over GF(q)

Kybernetika, 1986
Summary: This paper deals with the construction of codes over GF(q), q prime, by annexing two triangular matrices, one upper triangular and the other lower triangular. The error-correction capabilities of such codes are also studied.
