Improved Coding over Sets for DNA-Based Data Storage
Hengjia Wei, Moshe Schwartz
Error-correcting codes over sets, with applications to DNA storage, are studied. The DNA-storage channel receives a set of sequences, and produces a corrupted version of the set, i…
On the Gap between Scalar and Vector Solutions of Generalized Combination Networks
Hedongliang Liu, Hengjia Wei, Sven Puchinger +2
We study scalar-linear and vector-linear solutions of the generalized combination network. We derive new upper and lower bounds on the maximum number of nodes in the middle layer,…
On Tilings of Asymmetric Limited-Magnitude Balls
Hengjia Wei, Moshe Schwartz
We study whether an asymmetric limited-magnitude ball may tile . This ball generalizes previously studied shapes: crosses, semi-crosses, and quasi-crosses. Such tilin…
On Lattice Packings and Coverings of Asymmetric Limited-Magnitude Balls
Hengjia Wei, Xin Wang, Moshe Schwartz
We construct integer error-correcting codes and covering codes for the limited-magnitude error channel with more than one error. The codes are lattices that pack or cover the space…
