Lossless Data Compression at Finite Blocklengths
, 2012 This paper provides an extensive study of the behavior of the best achievable rate (and other related fundamental limits) in variable-length lossless compression. In the non-asymptotic regime, the fundamental limits of fixed-to-variable lossless compression with and without prefix constraints are shown to be tightly coupled.

Energy-efficient algorithms for lossless data compression schemes in wireless sensor networks
Scientific AfricanWireless sensor networks (WSNs) are reliant on limited power resources, primarily provided by small batteries within sensor nodes. Inefficient energy management within these networks can lead to premature battery depletion during data transmission ...

ISSDC: Digram Coding Based Lossless Data Compression Algorithm
COMPUTING AND INFORMATICS, 2010 In this paper, a new lossless data compression method that is based on digram coding is introduced. This data compression method uses semi-static dictionaries: All of the used characters and most frequently used two character blocks (digrams) in the source are found and inserted into a dictionary in the first pass, compression is performed in the ...

Empirical Lossless Compression Bound of a Data Sequence
EntropyWe consider the lossless compression bound of any individual data sequence. Conceptually, its Kolmogorov complexity is such a bound yet uncomputable. According to Shannon’s source coding theorem, the average compression bound is nH, where n is the number

Lossless data compression of radio astronomy data
, 2016 A compression algorithm designed for radio astronomy data is developed in this project. Real data from both ALMA and SKA projects is analyzed. A pre-compression and post-compression algorithm is implemented and integrated with the compressor FAPEC. The results are compared to both GZIP and BZIP2.

Lossless Data Compression Using Cellular Automata
, 2012 This thesis presents an investigation into the idea of using Cellular Automata to compress digital data. The approach is based on the fact that many CA configurations have a previous configuration, but only one next generation. By going backwards and finding a smaller configuration we can store that configuration and how many steps to go forward ...
