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…

The convolution sum $\sum_{a l + bm = n} σ (l) σ (m)$ for $(a, b) = (1, 28), (4, 7), (1, 14), (2, 7), (1, 7)$

Ayşe Alaca, Şaban Alaca, Ebénézer Ntienjem

We evaluate the convolution sum $W_{a, b} (n) := a l + bm = n \sum σ (l) σ (m)$ for $(a, b) = (1, 28), (4, 7), (2, 7)$ for all positive integers $n$ . We use a modular…
