Generalized Singleton Type Upper Bounds
Hao Chen, Longjiang Qu, Chengju Li +2
In this paper, we give upper bounds on the sizes of list-decodable codes in the Hamming metric space from covering codes with the covering radius smaller than or equal to…
Storage and Retrieval Codes in PIR Schemes with Colluding Servers
Hao Chen, Liqing Xu
Private information retrieval (PIR) schemes (with or without colluding servers) have been proposed for realistic coded distributed data storage systems. Star product PIR schemes wi…
New Constructions of Subspace Codes Using Subsets of MRD codes in Several Blocks
Hao Chen, Xianmang He, Jian Weng +1
A basic problem for the constant dimension subspace coding is to determine the maximal possible size A_q (n, d, k) of a set of k-dimensional subspaces in Fnq such that the subspace…
New -ary Quantum MDS Codes with Distances Bigger than
Xianmang He, Liqing Xu, Hao Chen
Constructions of quantum MDS codes have been studied by many authors. We refer to the table in page 1482 of [3] for known constructions. However there are only few -ary quantum…
Deterministic Construction of RIP Matrices in Compressed Sensing from Constant Weight Codes
Liqing Xu, Hao Chen
The expicit restricted isometry property (RIP) measurement matrices are needed in practical application of compressed sensing in signal processing. RIP matrices from Reed-Solomon c…
New Explicit Binary Constant Weight Codes from Reed-Solomon Codes
Liqing Xu, Hao Chen
Binary constant weight codes have important applications and have been studied for many years. Optimal or near-optimal binary constant weight codes of small lengths have been deter…
