P. 1–4.
A. M. Veresova, A. A. Ovchinnikov
The main concepts of the metric description of memory channels are considered, as well as a specific metric for
such channels. The spectral properties of the Gilbert code in relation to the Markov metric are analyzed. It is shown that using a matched metric increases the efficiency of channel usage.

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. ...

The article discusses the data transmission using convolutional codes over channels where the noise process can be described by a Markov chain with two states: a simple binary Markov channel and the Gilbert channel. Using the classical Viterbi algorithm with the Hamming metric for these channels does not guarantee low error probabilities. Additionally, the use ...

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 article investigates inter-cultural artistic communication which occurs through multimodal texts in general and feature films in particular. Artistic communication faces a challenge when its source and target belong to different ethnic and/or generational cohorts. The similarity or difference of communication codes depends on the level of adequacy of the sender’s and the recipient’s discursive ...

The novel methods for binary discrete Fourier transform (DFT) computation over the finite field have been proposed. The methods are based on a binary trace calculation over the finite field and use the cyclotomic DFT.

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 ...

Unlike most papers devoted to improvements of code-based cryptosystem, where original Goppa codes are substituted by some other codes, we suggest a new method of strengthening which is code-independent.
