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…
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…
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…
