Efficient and Compact Representations of Some Non-canonical Prefix-Free Codes [PDF]

open access: yes, 2016
The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-46049-9_5[Abstract] For many kinds of prefix-free codes there are efficient and compact alternatives to the traditional tree-based representation.

Lossless quantum prefix compression for communication channels that are always open [PDF]

open access: yes, 2009
We describe a method for lossless quantum compression if the output of the information source is not known. We compute the best possible compression rate, minimizing the expected base length of the output quantum bit string (the base length of a quantum ...

Complete Variable-Length "Fix-Free" Codes

open access: yes, 1995
A set of codewords is fix-free if it is both prefix-free and suffix-free: no codeword in the set is a prefix or a suffix of any other. A set of codewords fx 1 ; x 2 ; : : : ; x n g over a t-letter alphabet \Sigma is said to be complete if it satisfies ...

Arithmetic coding revisited

open access: yes, 1998
Over the last decade, arithmetic coding has emerged as an important compression tool. It is now the method of choice for adaptive coding on multisymbol alphabets because of its speed, low storage requirements, and effectiveness of compression.

Optimal Prefix-Free Codes for Unequal Letter Costs: Dynamic Programming with the Monge Property

open access: yes, 2002
In this paper we discuss the problem of finding optimal prefix-free codes for unequal letter costs, a variation of the classical Huffman coding problem.

Rate of prefix-free codes in LQG control systems

open access: yes, 2016
In this paper, we consider a discrete time linear quadratic Gaussian (LQG) control problem in which state information of the plant is encoded in a variable-length binary codeword at every time step, and a control input is determined based on the ...

Linear equalizers for quasi-synchronous block spreading CDMA systems [PDF]

open access: yes, 2009
Recently, a block spreading code division multiple access (BS-CDMA) technique was presented whereby user-specific preceding along with orthogonal spreading codes are used to achieve multi-user interference (MUI) free when all users arrive at the base ...

Topics in Lossless Source and Channel Coding [PDF]

open access: yes, 2023
This dissertation studies several topics in lossless source and channel coding, including: hexagonal run-length-limited constraints; fix-free codes; characterizations of minimal expected length codes; and the competitive advantage of prefix ...
