CRC-Aided Parity-Check Polar Coding
IEEE Access, 2019 Parity-check (PC) polar codes can yield better error-correcting performance compared with the cyclic redundancy check (CRC) aided polar codes under successive cancellation list decoder.

Rate‐compatible systematic polar codes
IET Communications, 2021 Puncturing and shortening are two common ways to achieve rate‐compatible non‐systematic polar codes (NSPCs). Systematic polar codes (SPCs) have been shown to outperform NSPCs with the same encoding and decoding complexity.

Polar Codes for Automorphism Ensemble Decoding
, 2021 International audienceIn this paper we deal with polar code automorphisms that are beneficial under low-latency automorphism ensemble (AE) decoding, and we propose polar code designs that have such automorphisms. Successive-cancellation (SC) decoding and

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

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 ...

Polar Codes for Multiple Descriptions [PDF]
IEEE Transactions on Information Theory, 2014 A polar coding scheme is proposed for the multiple description coding (MDC) problem and is shown to be able to achieve a certain rate pair on the dominant line of the achievable rate region determined by El Gamal and Cover. This scheme is an adaptation of the one developed by ŗasoglu et al. for the multiple access channel (MAC) to the MDC setting.

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
