To improve the traditional NOMA system, a hybrid approach is used, as well as the iterative detection and decoding (IDD) method for LDPC-coded SCMA systems to improve reliability. However, most research focused on downlink multiple access transmission. In this study, we focus on uplink multiple access and propose the SCMA-SIC process, which integrates IDD and SIC concepts. We also compare the performance of different NOMA receiver designs, including IDD, hybrid-domain NOMA, and our proposed schemes. Finally, three different power control strategies are used to improve system performance.
