About Usage of Metrics in Decoding of LDPC Codes in Two-State Channels with Memory
P. 143–148.
The applying of low-density parity-check codes is
considered over two-state channels with memory described by
Markov and Gilbert models. The error probability using different
strategies of syndrome decoding is estimated. The method of
choosing the coset leaders is proposed which provides the
error probability close to maximum-likelihood decoding for the
considered codes.

Modern representation learning increasingly relies on unsu-pervised and self-supervised methods trained on large-scale unlabeled data. While these approaches achieve impressive generalization across tasks and domains, evaluating embedding quality without labels remains an open challenge. In this work, we propose Persistence, a topology-aware metric based on persistent homology that quantifies the geomet-ric structure and topological richness ...

Product code construction is a powerful error-correcting tool for both channels with and without memory. The common approach to decoding product (iterative) code is to apply consequent decoders in a sequential manner. The paper examines the influence of memory in the channel on iterative decoding for hard decision, soft decision, and trellis-based decoding algorithms. Also, ...

When transmitting information over channels with grouping errors, the traditional approach is channel decorrelation and use of codes correcting independent errors. The decorrelation procedure lowers achievable rates of reliable transmission, therefore the problem of using special codes for channels with memory and construction of computationally effective decoding methods for correction of grouping errors is actual. ...

This article explores the metrics of poems written by the poet Antonina A. Kymytval. The meter of the verse, written in Chukchi, has not been explored before. I collected a corpus of 40 texts and glossed them manually. After that, I analyzed the number of syllables in a line and the placement of word boundaries, stress, and syllables ...

Error correction during data storage, processing, and transmission allows for ensuring data integrity. Channel coding
techniques are used to counteract these errors. Noise in real systems is often correlated, whereas traditional coding
and decoding approaches are based on decorrelation which in turn reduces the performance limits of channel coding.
Polar codes, adopted as a coding scheme in the ...

The common technique to perform decoding in channels with memory is to use interleaving, which increases both complexity and delay at the receiver. To overcome these limitations, coding scheme adaptation approaches might be used. One of the approaches is the optimization of long error-correcting codes and the modification of the decoder, taking into account the ...

Satellite and space communication systems have received a lot of attention as crucial transmission frameworks in recent years. In these systems, the signal is mostly degraded by fast amplitude and phase changes (fading), which cause error bursts. Hence, robust error-correcting codes that can handle error bursts are necessary for space and satellite transmissions of good ...

In modern systems for communication, data storage and processing the error-correction capability of codes are estimated for memoryless channels. In real channels the noise is correlated, which leads to grouping error in bursts. A traditional method to fight this phenomenon is channel decorrelation, which does not allow developing of coding schemes, mostly utilizing the channel ...

Although low-density parity-check (LDPC) codes in modern communication standards have been extensively studied over a memoryless channel, their burst error correction capacity in channels with memory has yet to be
thoroughly analyzed. The conventional approach to transmission in channels with memory uses interleaving within
a buffer of several codewords. However, such an approach reduces the efficiency of ...
