On the Capacity Comparison Between MIMO-NOMA and MIMO-OMA
Non-orthogonal multiple access (NOMA) has been shown in the literature to have a better performance than OMA in terms of sum channel capacity; however, the capacity superiority of NOMA over OMA has been only proved for single antenna systems, and the ...

New Variable-Weight Optical Orthogonal Codes with Weights 3 to 5
In optical networks, designing optical orthogonal codes (OOCs) with appropriate parameters is essential for enhancing the overall system performance. They are divided into two categories, constant-weight OOCs (CW-OOCs) and variable-weight OOCs (VW-OOCs),

Coding for a multiple-access channel
The channel considered here is a real-number adder. Attention is restricted to the case of two sources using binary signals; hence the channel has a ternary output. The paper treats both the noiseless and noisy situations. For the noiseless case the following results are obtained: several code-construction techniques are presented; a Gilbert-like lower
