Dual‐mode codeword position index based SCMA with transmit diversity

IET Communications
Codeword position index based sparse code multiple access (CPI‐SCMA) is an effective scheme that expands codeword positions in the time domain and carries extra information by their index.

Design of Enhanced Protograph Codes and Codebooks for IDD-SCMA Systems

IEEE Access
This paper investigates the design of protograph low-density parity-check (PLDPC) codes and Gray-labeling codebooks (CBs) for the sparse code multiple access systems with iterative detection and decoding receiver (IDD-SCMA).

Deep Learning Multi-User Detection for PD-SCMA

IEEE Access
The performance of hybrid multi-radio access technologies depends on the sufficiency of the multi-user detection (MUD) at the receiver. For optimal performance of the hybrid power-domain sparse code multiple access (PD-SCMA), robust detection strategies ...
