Low-Density Spreading Design Based on an Algebraic Scheme for NOMA Systems
Goldwyn Millar, Michel Kulhandjian, Ayse Alaca +3
NOMA) technique based on an algebraic design is studied. We propose an improved low-density spreading (LDS) sequence design based on projective geometry. In terms of its bit error…
Jacobi Sums and Correlations of Sidelnikov Sequences
Ayse Alaca, Goldwyn Millar
We consider the problem of determining the cross-correlation values of the sequences in the families comprised of constant multiples of -ary Sidelnikov sequences over $\mathbb{F…
Shift-Inequivalent Decimations of the Sidelnikov-Lempel-Cohn-Eastman Sequences
Saban Alaca, Goldwyn Millar
We consider the problem of finding maximal sets of shift-inequivalent decimations of Sidelnikov-Lempel-Cohn-Eastman (SLCE) sequences (as well as the equivalent problem of determini…
Character Values of the Sidelnikov-Lempel-Cohn-Eastman Sequences
Şaban Alaca, Goldwyn Millar
Binary sequences with good autocorrelation properties and large linear complexity are useful in stream cipher cryptography. The Sidelnikov-Lempel-Cohn-Eastman (SLCE) sequences have…
Hankel Weighing Matrices
Goldwyn Millar
We prove a classification theorem for Hankel weighing matrices.
