Improved constructions of permutation and multi-permutation codes correcting a burst of stable deletions
Yubo Sun, Yiwei Zhang, Gennian Ge
Permutation codes and multi-permutation codes have been widely considered due to their various applications, especially in flash memory. In this paper, we consider permutation code…
Coding schemes for locally balanced constraints
Chen Wang, Ziyang Lu, Zhaojun Lan +2
Motivated by applications in DNA-based storage, we study explicit encoding and decoding schemes of binary strings satisfying locally balanced constraints, where the -loca…
t-Deletion-s-Insertion-Burst Correcting Codes
Ziyang Lu, Yiwei Zhang
Motivated by applications in DNA-based storage and communication systems, we study deletion and insertion errors simultaneously in a burst. In particular, we study a type of error…
Private Proximity Retrieval Codes
Yiwei Zhang, Eitan Yaakobi, Tuvi Etzion
A \emph{private proximity retrieval} (\emph{PPR}) scheme is a protocol which allows a user to retrieve the identities of all records in a database that are within some distance …
Bounds on the Length of Functional PIR and Batch codes
Yiwei Zhang, Eitan yaakobi, Tuvi Etzion
A functional -PIR code of dimension consists of servers storing linear combinations of linearly independent information symbols. Any linear combination of the 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…
On the Access Complexity of PIR Schemes
Yiwei Zhang, Eitan Yaakobi, Tuvi Etzion +1
Private information retrieval has been reformulated in an information-theoretic perspective in recent years. The two most important parameters considered for a PIR scheme in a dist…
Private Information Retrieval from MDS Coded Databases with Colluding Servers under Several Variant Models
Yiwei Zhang, Gennian Ge
Private information retrieval (PIR) gets renewed attentions due to its information-theoretic reformulation and its application in distributed storage system (DSS). The general PIR…
A general private information retrieval scheme for MDS coded databases with colluding servers
Yiwei Zhang, Gennian Ge
The problem of private information retrieval gets renewed attentions in recent years due to its information-theoretic reformulation and applications in distributed storage systems.…
New bounds of permutation codes under Hamming metric and Kendall's -metric
Xin Wang, Yiwei Zhang, Yiting Yang +1
Permutation codes are widely studied objects due to their numerous applications in various areas, such as power line communications, block ciphers, and the rank modulation scheme f…
On private information retrieval array codes
Yiwei Zhang, Xin Wang, Hengjia Wei +1
Given a database, the private information retrieval (PIR) protocol allows a user to make queries to several servers and retrieve a certain item of the database via the feedbacks, w…
Centralized coded caching schemes: A hypergraph theoretical approach
Chong Shangguan, Yiwei Zhang, Gennian Ge
The centralized coded caching scheme is a technique proposed by Maddah-Ali and Niesen as a solution to reduce the network burden in peak times in a wireless system. Later Yan et al…
New Constructions of MDS Symbol-Pair Codes
Baokun Ding, Gennian Ge, Jun Zhang +2
Motivated by the application of high-density data storage technologies, symbol-pair codes are proposed to protect against pair-errors in symbol-pair channels, whose outputs are ove…
Invertible binary matrix with maximum number of -by- invertible submatrices
Yiwei Zhang, Tao Zhang, Xin Wang +1
The problem is related to all-or-nothing transforms (AONT) suggested by Rivest as a preprocessing for encrypting data with a block cipher. Since then there have been various applic…
Snake-in-the-Box Codes for Rank Modulation under Kendall's -Metric
Yiwei Zhang, Gennian Ge
For a Gray code in the scheme of rank modulation for flash memories, the codewords are permutations and two consecutive codewords are obtained using a push-to-the-top operation. We…
