Almost difference sets and their sequences with optimal autocorrelation
Almost difference sets have interesting applications in cryptography and coding theory. Expand
Two-dimensional perfect quaternary arrays
We study two-dimensional (2-D) arrays of fourth roots of unity which have all out-of-phase periodic autocorrelations equal to zero. Expand
Some New Difference Sets
We construct (96, 20, 4) difference sets, thereby filling a missing entry in Lander's table with the answer “yes”. Expand
Self-dual codes over Fp and weighing matrices
Self-dual codes constructed from Hadamard matrices and conference matrices . Expand

The existence status of previously open cases of circulant weighing matrices will be established using various techniques. Expand
On the existence of periodic complementary binary sequences
Using the connection between periodic complementary binary sequences and difference families given by Bömer and Antweiler [2], we use number theoretic techniques to obtain necessary conditions for their existence when two or three sequences are involved. Expand

Binary perfect sequences and their variations have applications in various areas such as signal processing, synchronizing and distance measuring radars. Expand
Study of proper circulant weighing matrices with weight 9
We provide the first theoretical proof of the spectrum of orders n for which circulant weighing matrices with weight 9 exist. Expand
