Polar codes: Encoding/decoding and rate-compatible jointly design for HARQ system
Intelligent and Converged Networks, 2021 Polar coding are the first class of provable capacity-achieving coding techniques for a wide range of channels. With an ideal recursive structure and many elegant mathematical properties, polar codes are inherently implemented with low complexity ...

On the Construction and Decoding of Concatenated Polar Codes
, 2013 A scheme for concatenating the recently invented polar codes with interleaved block codes is considered. By concatenating binary polar codes with interleaved Reed-Solomon codes, we prove that the proposed concatenation scheme captures the capacity ...

An efficient length- and rate-preserving concatenation of polar and repetition codes
, 2013 We improve the method in \cite{Seidl:10} for increasing the finite-lengh performance of polar codes by protecting specific, less reliable symbols with simple outer repetition codes.

Modified pilot selection for channel estimation of systematic polar coded MIMO-OFDM
ICT Express, 2019 This paper proposes a modified pilot selection for channel estimation of systematic polar coded MIMO-OFDM. Polar codes provably achieve the theoretical limit for communication systems and systematic polar codes generate the codeword that has the same ...

List Decoding of Arıkan’s PAC Codes
Entropy, 2021 Polar coding gives rise to the first explicit family of codes that provably achieve capacity with efficient encoding and decoding for a wide range of channels. However, its performance at short blocklengths under standard successive cancellation decoding

Polar Codes for Broadcast Channels [PDF]
IEEE 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.

Fast Software Polar Decoders [PDF]
, 2014 Among error-correcting codes, polar codes are the first to provably achieve channel capacity with an explicit construction. In this work, we present software implementations of a polar decoder that leverage the capabilities of modern general-purpose ...

Polar-Coded Transmission over 7.8-km Terrestrial Free-Space Optical Links
Photonics, 2023 Free-space optical (FSO) communications can offer high-capacity transmission owing to the properties of the laser beams. However, performance degradation caused by atmospheric turbulence is an urgent issue. Recently, the application of polar codes, which

Comparison of Polar Decoders with Existing Low-Density Parity-Check and Turbo Decoders
, 2017 Polar codes are a recently proposed family of provably capacity-achieving error-correction codes that received a lot of attention. While their theoretical properties render them interesting, their practicality compared to other types of codes has not ...
