Private Information Retrieval over Graphs
Gennian Ge, Hao Wang, Zixiang Xu +1
The problem of PIR in graph-based replication systems has received significant attention in recent years. A systematic study was conducted by Sadeh, Gu, and Tamo, where each file i…
Optimal Reconstruction Codes with Given Reads in Multiple Burst-Substitutions Channels
Wenjun Yu, Yubo Sun, Zixiang Xu +2
We study optimal reconstruction codes over the multiple-burst substitution channel. Our main contribution is establishing a trade-off between the error-correction capability of the…
Optimal redundancy of function-correcting codes
Gennian Ge, Zixiang Xu, Xiande Zhang +1
Function-correcting codes, introduced by Lenz, Bitar, Wachter-Zeh, and Yaakobi, protect specific function values of a message rather than the entire message. A central challenge is…
A generic framework for coded caching and distributed computation schemes
Min Xu, Zixiang Xu, Gennian Ge +1
Several network communication problems are highly related such as coded caching and distributed computation. The centralized coded caching focuses on reducing the network burden in…
New Theoretical Bounds and Constructions of Permutation Codes under Block Permutation Metric
Zixiang Xu, Yiwei Zhang, Gennian Ge
Permutation codes under different metrics have been extensively studied due to their potentials in various applications. Generalized Cayley metric is introduced to correct generali…
