On the Origin of Polar Coding [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2016
Polar coding was conceived originally as a technique for boosting the cutoff rate of sequential decoding, along the lines of earlier schemes of Pinsker and Massey. The key idea in boosting the cutoff rate is to take a vector channel (either given or artificially built), split it into multiple correlated subchannels, and employ a separate sequential ...

Polar Code decoder exploration framework [PDF]

open access: yesAdvances in Radio Science, 2018
The increasing demand for fast wireless communications requires sophisticated baseband signal processing. One of the computational intense tasks here is advanced Forward Error Correction (FEC), especially the decoding.

A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes

open access: yesDianxin 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

open access: yesIEEE 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 ...

Polar Codes for Broadcast Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.

Multi-CRC Polar Codes and M-SCFlip-Based Decoding

open access: yesIEEE Access, 2019
A multi-cyclic redundancy check (Multi-CRC) polar code construction algorithm is proposed in this paper to solve the error propagation problem of successive cancellation decoding for polar codes.

Low Power, Area Efficient Architecture for Successive Cancellation Decoder

open access: yesEmitter: 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.

Performance comparison of systematic polar code and non-systematic polar code

open access: yesTongxin xuebao, 2019
Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For ...

Generalized Partially Information Coupled Polar Codes With Arbitrary Coupling Depth and Their Decoding Algorithms

open access: yesIEEE 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
