QC-LDPC Codes from Difference Matrices and Difference Covering Arrays

Diane Donovan, Asha Rao, Elif Üsküplü +1

We give a framework for generalizing LDPC code constructions that use Transversal Designs or related structures such as mutually orthogonal Latin squares. Our construction offers a…

Equivalences of $Z_{t} \times Z_{2}^{2}$ -cocyclic Hadamard matrices

V. Alvarez, F. Gudiel, M. B. Guemes +2

One of the most promising structural approaches to resolving the Hadamard Conjecture uses the family of cocyclic matrices over $Z_{t} \times Z_{2}^{2}$ . Two types of…
