Polar Coding for Confidential Broadcasting [PDF]
Entropy, 2020 A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send the same private (non-confidential) message and the same confidential message reliably to two different legitimate receivers, and the confidential message must also be ...

A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes
Dianxin kexue, 2021 Polar codes have perfect coding and decoding performance as a kind of error correction code, which have become a standard coding scheme for 5G short code control channel. While the length of polar codes is short, its performance is not good enough.

Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability
IEEE Access, 2019 A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...

Low Power, Area Efficient Architecture for Successive Cancellation Decoder
Emitter: International Journal of Engineering Technology, 2022 Polar codes have recently emerged as an error-correcting code and have become popular owing to their capacity-achieving nature. Polar code based communication system primarily consists of two parts, including Polar Encoder and Decoder.

Flexible and Low-Complexity Encoding and Decoding of Systematic Polar Codes [PDF]
, 2016 In this work, we present hardware and software implementations of flexible polar systematic encoders and decoders. The proposed implementations operate on polar codes of any length less than a maximum and of any rate.

Multilevel polar-coded modulation [PDF]
2013 IEEE International Symposium on Information Theory, 2013 A framework is proposed that allows for a joint description and optimization of both binary polar coding and the multilevel coding (MLC) approach for $2^m$-ary digital pulse-amplitude modulation (PAM). The conceptual equivalence of polar coding and multilevel coding is pointed out in detail. Based on a novel characterization of the channel polarization

IEEE Access, 2021 We propose generalized partially information coupled (PIC) polar codes and their construction method. In the proposed codes, each code block (CB) shares systematic information bits partially with J adjacent CBs on each side, where J is referred to as the

Design of concatenated Hash-Polar code based on segmented CRC code
Dianxin kexue, 2022 As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic

Polar Codes with exponentially small error at finite block length [PDF]
, 2018 We show that the entire class of polar codes (up to a natural necessary condition) converge to capacity at block lengths polynomial in the gap to capacity, while simultaneously achieving failure probabilities that are exponentially small in the block ...
