Construction of MRD Codes Based on Circular-Shift Operations

Zhe Zhai, Sheng Jin, Qifu Tyler Sun +1

Most well-known constructions of $(N \times n, q^{N k}, d)$ maximum rank distance (MRD) codes rely on the arithmetic of $F_{q^{N}}$ , whose increasing complexity with larger $…

Generic Construction of Optimal-Access Binary MDS Array Codes with Smaller Sub-packetization

Lan Ma, Qifu Tyler Sun, Shaoteng Liu +1

A $(k + r, k, l)$ binary array code of length $k + r$ , dimension $k$ , and sub-packetization $l$ is composed of $l \times (k + r)$ matrices over $F_{2}$ , with every column of the matri…

Circular-shift-based Vector Linear Network Coding and Its Application to Array Codes

Sheng Jin, Zhe Zhai, Qifu Tyler Sun +1

Circular-shift linear network coding (LNC) is a class of vector LNC with local encoding kernels selected from cyclic permutation matrices, so that it has low coding complexities. H…
