A Low-Density Code Structure (LDC) spread transmission for Non-Orthogonal Multiple Access (NOMA) system based on modified combinatorial design is studied in this letter. To mitigate the multiuser access interference, the NOMA frequently needs complicated signal processing, which is difficult to be applied in practical scenarios. One potential solution is to design sparse multiple access structure for leveraging detection complexity.
