A Note on the Mixing Factor of Polar Codes [PDF]
Entropy, 2023 Over binary-input memoryless symmetric (BMS) channels, the performance of polar codes under successive cancellation list (SCL) decoding can approach maximum likelihood (ML) algorithm when the list size L is greater than or equal to 2MF, where MF, known ...

Hash-Polar Codes With Application to 5G
IEEE Access, 2019 This paper presents a kind of concatenated polar codes called hash-polar codes with flexible outer code lengths, in which a hash function-based encoder is used as an outer encoder.

Distributed Joint Source-Channel Coding Using Quasi-Uniform Systematic Polar Codes [PDF]
Entropy, 2018 This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only ...

On Training Neural Network Decoders of Rate Compatible Polar Codes via Transfer Learning [PDF]
Entropy, 2020 Neural network decoders (NNDs) for rate-compatible polar codes are studied in this paper. We consider a family of rate-compatible polar codes which are constructed from a single polar coding sequence as defined by 5G new radios.

Polarization and Polar Codes [PDF]
Foundations and Trends® in Communications and Information Theory, 2012 This tutorial treats the fundamentals of polarization theory and polar coding. Arikan’s original results on binary source and channel polarization methods are studied. Error probability and complexity analyses are offered. The original results are generalized in several directions.

Concatenated Polar codes [PDF]
2010 IEEE International Symposium on Information Theory, 2010 Polar codes have attracted much recent attention as the first codes with low computational complexity that provably achieve optimal rate-regions for a large class of information-theoretic problems. One significant drawback, however, is that for current constructions the probability of error decays sub-exponentially in the block-length (more detailed ...

Differential properties of polar codes [PDF]
E3S Web of Conferences, 2023 This paper discusses the features of polar coding as a differential encoder for a binary erasure channel. One of the modern methods of error-correcting coding is polar codes, which has great prospects in the development of current and future wireless ...

On the construction of polar codes [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 We consider the problem of efficiently constructing polar codes over binary memoryless symmetric (BMS) channels. The complexity of designing polar codes via an exact evaluation of the polarized channels to find which ones are "good" appears to be exponential in the block length.

Low Latency SC Decoder Architecture for Interleaved Polar Codes [PDF]
Radioengineering, 2022 Interleaved polar (I-Polar) codes, a new facet of polar codes to achieve better channel capacity, is designed by placing the interleaver and deinterleaver blocks midway between the stages of the polar codes.

Nonbinary polar coding with low decoding latency and complexity
Journal of Information and Intelligence, 2023 In this paper, we propose a new class of nonbinary polar codes, where the symbol-level polarization is achieved by using a 2 × 2 q-ary matrix 10β1 as the kernel.
