Polar codes and polar lattices for the Heegard-Berger problem [PDF]
, 2017 Explicit coding schemes are proposed to achieve the rate-distortion function of the Heegard-Berger problem using polar codes. Specifically, a nested polar code construction is employed to achieve the rate-distortion function for doublysymmetric binary ...

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 ...

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 ...

Efficient Implementation of Density Evolution for Punctured Polar Codes
IEEE Access, 2019 Polar codes asymptotically achieve the symmetric capacity of arbitrary binary-input discrete memoryless channels under low-complexity sequential decoding algorithms such as successive cancellation decoding.

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.

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

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.

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

Reed-Muller Codes Polarize [PDF]
2019 IEEE 60th Annual Symposium on Foundations of Computer Science (FOCS), 2019 Reed-Muller (RM) codes and polar codes are generated by the same matrix $G_m= \bigl[\begin{smallmatrix}1 & 0 \\ 1 & 1 \\ \end{smallmatrix}\bigr]^{\otimes m}$ but using different subset of rows. RM codes select simply rows having largest weights.
