Polarity-balanced codes

open access: yes2013 Information Theory and Applications Workshop (ITA), 2013
Balanced bipolar codes consist of sequences in which the symbols ‘−1’ and ‘+1’ appear equally often. Several generalizations to larger alphabets have been considered in literature. For example, for the q-ary alphabet {−q + 1, −q + 3, …, q − 1}, known concepts are symbol balancing, i.e., all alphabet symbols appear equally often in each codeword, and ...

Serially Concatenated Polar Codes

open access: yesIEEE Access, 2018
Simulation results show that the performance of polar codes is improved vastly by using polar codes as inner codes in serially concatenated coding schemes.

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 ...

Efficient Implementation of Density Evolution for Punctured Polar Codes

open access: yesIEEE 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

open access: yesIEEE 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

open access: yesIET 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.

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
