Access Balancing in Storage Systems by Labeling Partial Steiner Systems
Yeow Meng Chee, Charles J. Colbourn, Hoang Dau +4
Storage architectures ranging from minimum bandwidth regenerating encoded distributed storage systems to declustered-parity RAIDs can be designed using dense partial Steiner system…
Optimal Partitioned Cyclic Difference Packings for Frequency Hopping and Code Synchronization
Yeow Meng Chee, Alan C. H. Ling, Jianxing Yin
Optimal partitioned cyclic difference packings (PCDPs) are shown to give rise to optimal frequency-hopping sequences and optimal comma-free codes. New constructions for PCDPs, base…
Linear Size Optimal q-ary Constant-Weight Codes and Constant-Composition Codes
Yeow Meng Chee, Son Hoang Dau, Alan C. H. Ling +1
An optimal constant-composition or constant-weight code of weight has linear size if and only if its distance is at least . When , the determination of the…
Spectrum of Sizes for Perfect Deletion-Correcting Codes
Yeow Meng Chee, Gennian Ge, Alan C. H. Ling
One peculiarity with deletion-correcting codes is that perfect -deletion-correcting codes of the same length over the same alphabet can have different numbers of codewords, beca…
Group Divisible Codes and Their Application in the Construction of Optimal Constant-Composition Codes of Weight Three
Yeow Meng Chee, Gennian Ge, Alan C. H. Ling
The concept of group divisible codes, a generalization of group divisible designs with constant block size, is introduced in this paper. This new class of codes is shown to be usef…
The Sizes of Optimal q-Ary Codes of Weight Three and Distance Four: A Complete Solution
Yeow Meng Chee, Son Hoang Dau, Alan C. H. Ling +1
This correspondence introduces two new constructive techniques to complete the determination of the sizes of optimal q-ary codes of constant weight three and distance four.
The PBD-Closure of Constant-Composition Codes
Yeow Meng Chee, Alan C. H. Ling, San Ling +1
We show an interesting PBD-closure result for the set of lengths of constant-composition codes whose distance and size meet certain conditions. A consequence of this PBD-closure re…
