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.

Near-Extremal Type I Self-Dual Codes with Minimal Shadow over GF(2) and GF(4)

open access: yesInformation, 2018
Binary self-dual codes and additive self-dual codes over GF(4) contain common points. Both have Type I codes and Type II codes, as well as shadow codes. In this paper, we provide a comprehensive description of extremal and near-extremal Type I codes over

Fault-tolerant logical gates in quantum error-correcting codes [PDF]

open access: yes, 2014
Recently, Bravyi and K\"onig have shown that there is a tradeoff between fault-tolerantly implementable logical gates and geometric locality of stabilizer codes.

$\mathbb {F}_p$-Linear and $\mathbb {F}_{p^m}$-Linear Qudit Codes From Dual-Containing Classical Codes

open access: yesIEEE Transactions on Quantum Engineering, 2021
Quantum code construction from two classical codes $D_1[n,k_1,d_1]$ and $D_2[n,k_2,d_2]$ over the field $\mathbb {F}_{p^m}$ ($p$ is prime and $m$ is an integer) satisfying the dual containing criteria $D_1^{\perp } \subset D_2$ using the Calderbank ...

Low Complexity Encoding for Network Codes [PDF]

open access: yes, 2006
In this paper we consider the per-node run-time complexity of network multicast codes. We show that the randomized algebraic network code design algorithms described extensively in the literature result in codes that on average require a number of ...

Narain CFTs from nonbinary stabilizer codes

open access: yesJournal of High Energy Physics, 2023
We generalize the construction of Narain conformal field theories (CFTs) from qudit stabilizer codes to the construction from quantum stabilizer codes over the finite field of prime power order ( F p m $$ {\mathbbm{F}}_{p^m} $$ with p prime and m ≥ 1) or

Non-Binary LDPC Codes with Large Alphabet Size

open access: yes, 2014
We study LDPC codes for the channel with input ${x}\in \mathbb{F}_q^m$ and output ${y}={x}+{z}\in \mathbb{F}_q^m$. The aim of this paper is to evaluate decoding performance of $q^m$-ary non-binary LDPC codes for large $m$.

On Optimal Binary One-Error-Correcting Codes of Lengths $2^m-4$ and $2^m-3$

open access: yes, 2011
Best and Brouwer [Discrete Math. 17 (1977), 235-245] proved that triply-shortened and doubly-shortened binary Hamming codes (which have length $2^m-4$ and $2^m-3$, respectively) are optimal.

On the non-minimality of the largest weight codewords in the binary Reed-Muller codes [PDF]

open access: yes, 2011
The study of minimal codewords in linear codes was motivated by Massey who described how minimal codewords of a linear code define access structures for secret sharing schemes.
