High Rate LDPC Codes from Difference Covering Arrays
D. Donovan, A. Rao, E. Şule Yazıcı
This paper presents a combinatorial construction of low-density parity-check (LDPC) codes from difference covering arrays. While the original construction by Gallagher was by rando…
Orthogonal trades in complete sets of MOLS

A Heffter array is an matrix with nonzero entries from such that each row contains filled cells and each column contains …
Planar Difference Functions
Joanne L. Hall, Asha Rao, Diane Donovan
In 1980 Alltop produced a family of cubic phase sequences that nearly meet the Welch bound for maximum non-peak correlation magnitude. This family of sequences were shown by Wooter…
