Sparse and Balanced MDS Codes over Small Fields
Tingting Chen, Xiande Zhang
Maximum Distance Separable (MDS) codes with a sparse and balanced generator matrix are appealing in distributed storage systems for balancing and minimizing the computational load.…
Optimal Ternary Codes with Weight and Distance in -Metric
Xin Wei, Tingting Chen, Xiande Zhang
The study of constant-weight codes in -metric was motivated by the duplication-correcting problem for data storage in live DNA. It is interesting to determine the maximum s…
Optimal codes with small constant weight in -metric
Tingting Chen, Yiming Ma, Xiande Zhang
Motivated by the duplication-correcting problem for data storage in live DNA, we study the construction of constant-weight codes in -metric. By using packings and group div…
Optimal Fraction Repetition Codes for Access-Balancing in Distributed Storage
Wenjun Yu, Xiande Zhang, Gennian Ge
To solve the access-balancing problem in distributed storage systems, we introduce a new combinatorial model, called MinVar model for fractional repetition (FR) codes. Since FR cod…
Some New Results on Splitter Sets
Zuo Ye, Tao Zhang, Xiande Zhang +1
Splitter sets have been widely studied due to their applications in flash memories, and their close relations with lattice tilings and conflict avoiding codes. In this paper, we gi…
Repairing Generalized Reed-Muller Codes
Tingting Chen, Xiande Zhang
In distributed storage systems, both the repair bandwidth and locality are important repair cost metrics to evaluate the performance of a storage code. Recently, Guruswami and Woot…
