Low-complexity trellis decoding of linear block codes. [PDF]

, 1995
The authors introduce a new simple encoding technique which allows the design of a wide variety of linear block codes. They present a number of examples in which the most widely used codes (Reed-Muller, Hamming, Golay, optimum etc.) have been designed ...

Application of optimal p-ary linear codes to alphabet-optimal locally repairable codes

, 2022
Linear codes have widespread applications in data storage systems. There are two major contributions in this paper. We first propose infinite families of optimal or distance-optimal linear codes over Fp constructed from projective spaces.Moreover, a ...

Short Low-Rate Non-Binary Turbo Codes [PDF]

, 2012
A serial concatenation of an outer non-binary turbo code with different inner binary codes is introduced and analyzed. The turbo code is based on memory-1 time-variant recursive convolutional codes over high order fields.

From Product Codes to Structured Generalized LDPC Codes [PDF]

, 2010
Product codes, due to their relatively large minimum distance, are often seen as a natural solution for applications requiring low error floors.

Design of LDPC Codes: A Survey and New Results [PDF]

, 2006
This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining (near-)optimal degree distributions for LDPC code ensembles.

Rate adaptive binary erasure quantization with dual fountain codes [PDF]

, 2008
—In this contribution, duals of fountain codes are introduced and their use for lossy source compression is investigated. It is shown both theoretically and experimentally that the source coding dual of the binary erasure channel coding problem, binary ...

Optimal Population Coding, Revisited [PDF]

, 2011
Cortical circuits perform the computations underlying rapid perceptual decisions within a few dozen milliseconds with each neuron emitting only a few spikes.

Optimal Generalized Quasi-Polycyclic Codes over ${\mathbb{F}}_{\mathit{q}}+\mathit{u}{\mathbb{F}}_{\mathit{q}}$

Mathematics
This paper develops a structural and constructive theory of right generalized quasi-polycyclic (GQPC) codes over the finite chain ring R=Fq+uFq with u2=0, extending the existing field-based GQPC framework to a ring-theoretic setting.

An Embedding Strategy Using Q-Ary Convolutional Codes for Large and Small Payloads

Mathematics, 2021
Matrix embedding (ME) code is a commonly used steganography technique, which uses linear block codes to improve embedding efficiency. However, its main disadvantage is the inability to perform maximum likelihood decoding due to the high complexity of ...
