Probability updating-based adaptive hybrid coding

open access: yesTongxin xuebao, 2008
A probability updating mechanism was proposed for entropy coding. To achieve the best coding efficiency,probability updating based huffman code and structured code were jointly used,and the best context model was selected according as the correlation of ...

Maximal codeword lengths in Huffman codes [PDF]

open access: yes
The following question about Huffman coding, which is an important technique for compressing data from a discrete source, is considered. If p is the smallest source probability, how long, in terms of p, can the longest Huffman codeword be?

Quantum-inspired Huffman Coding

open access: yes, 2013
Huffman Compression, also known as Huffman Coding, is one of many compression techniques in use today. The two important features of Huffman coding are instantaneousness that is the codes can be interpreted as soon as they are received and variable length that is a most frequent symbol has length smaller than a less frequent symbol.

RECURSIVE GROUP CODING WITH DYNAMIC FREQUENCY MODELING

open access: yesРадіоелектронні і комп'ютерні системи, 2016
Task of entropy group coding of data for reduce of its statistical redundancy on base of recursive group coding is considered. Recursive group coding provides effective coding of symbols of large alphabets.

Joint Source-Channel Coding Using Variable-Length Error-Correcting Codes

open access: yesJournal of Engineering and Sustainable Development, 2010
This paper explores the performance of both source coding and error-correction in a single coding step. Such joint source-channel coding is done here using codewords of varying lengths that have particular distance properties with each other, which ...

HUFFMAN CODING AS A NONLINEAR DYNAMICAL SYSTEM [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2011
In this paper, source coding or data compression is viewed as a measurement problem. Given a measurement device with fewer states than the observable of a stochastic source, how can one capture their essential information? We propose modeling stochastic sources as piecewise-linear discrete chaotic dynamical systems known as Generalized Luröth Series ...

Huffman Deep Compression of Edge Node Data for Reducing IoT Network Traffic

open access: yesIEEE Access
Data compression at the Internet of Things (IoT) edge node aims to minimize data traffic in smart cities. The traditional Huffman Coding Algorithm (HCA) is shown as the most effective compression algorithm for sensor data.
