One Burst of t-Deletion and One Burst of t-Substitution Error-Correcting Codes
Yajuan Liu, Han Cai, Tolga M. Duman
Synchronization errors, including insertions, deletions, and substitutions, may occur in bursts in communication systems such as DNA data storage, file synchronization, and magneti…
Convertible Polynomial Evaluation Codes in the Merge Regime: A Skew-Polynomial Framework
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we develop an algebraic framework for merge-regime convertible codes that works directly with the polynomial-evaluation structure of the underlying codes. We charact…
Convertible Codes: MSR-to-MSR Conversion with Optimal Access and Bandwidth
Yumeng Yang, Han Cai, Xianfu Lei +1
In this paper, we study convertible codes in the merge regime and focus on the minimum storage regenerating (MSR) setting, where both the initial codes and the final code admit opt…
Locally Repairable Convertible Codes: Improved Lower Bound and General Construction
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we consider the convertible code with locally repairable property. We present an improved lower bound on access cost associated with . Then, we provide a gen…
A New Cooperative Repair Scheme with Small Finite Field for Distributed Storage Systems
Yajuan Liu, Han Cai, Xiaohu Tang
In this paper, we consider the multiple failures in the distributed storage systems under the cooperative repair model. We introduce a new cooperative repair scheme for the (n,k,d,…
Repairing Schemes for Tamo-Barg Codes
Han Cai, Ying Miao, Moshe Schwartz +1
In this paper, the repair problem for erasures beyond locality in locally repairable codes is explored under a practical system setting, where a rack-aware storage system consists…
