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…
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.
Constructions for Difference Triangle Sets
Yeow Meng Chee, Charles J. Colbourn
Difference triangle sets are useful in many practical problems of information transmission. This correspondence studies combinatorial and computational constructions for difference…
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…
