Generalized Repetition Codes and Their Application to HARQ
Chaofeng Guan, Gaojun Luo, Lan Luo +2
The inherent uncertainty of communication channels implies that any coding scheme has a non-zero probability of failing to correct errors, making retransmission mechanisms essentia…
Lower Bounds for Error Coefficients of Griesmer Optimal Linear Codes via Iteration
Chaofeng Guan, Shitao Li, Gaojun Luo +2
The error coefficient of a linear code is defined as the number of minimum-weight codewords. In an additive white Gaussian noise channel, optimal linear codes with the smallest err…
Geometry of the symplectic group and optimal EAQECC codes
Ruihu Li, Yuezhen Ren, Chaofeng Guan +1
A new type of link between geometry of symplectic group and entanglement-assisted (EA) quantum error-correcting codes (EAQECCs) is presented. Relations of symplectic subspaces and…
Combinatorial Constructions of Optimal Quaternary Additive Codes
Chaofeng Guan, Jingjie Lv, Gaojun Luo +1
This paper aims to construct optimal quaternary additive codes with non-integer dimensions. Firstly, we propose combinatorial constructions of quaternary additive constant-weight c…
Some quaternary additive codes outperform linear counterparts
Chaofeng Guan, Ruihu Li, Yiting Liu +1
The additive codes may have better parameters than linear codes. However, it is still a challenging problem to efficiently construct additive codes that outperform linear codes, es…
On Euclidean, Hermitian and symplectic quasi-cyclic complementary dual codes
Chaofeng Guan, Ruihu Li, Zhi Ma
Linear complementary dual codes (LCD) intersect trivially with their dual. In this paper, we develop a new characterization for LCD codes, which allows us to judge the complementar…
Symplectic self-orthogonal quasi-cyclic codes
Chaofeng Guan, Ruihu Li, Jingjie Lv +1
In this paper, we establish the necessary and sufficient conditions for quasi-cyclic (QC) codes with index even to be symplectic self-orthogonal. Subsequently, we present the lower…
On construction of quantum codes with dual-containing quasi-cyclic codes
Chaofeng Guan, Ruihu Li, Liangdong Lu +2
One of the main objectives of quantum error-correction theory is to construct quantum codes with optimal parameters and properties. In this paper, we propose a class of 2-generator…
New Binary Quantum Codes Constructed from Quasi-Cyclic Codes
Chaofeng Guan, Ruihu Li, Liangdong Lu +1
It is well known that quantum codes can be constructed by means of classical symplectic dual-containing codes. This paper considers a family of two-generator quasi-cyclic codes and…
