Wireless Powered Cooperative Communication Network for Dual-Hop Uplink NOMA with IQI and SIC Imperfections

Non-orthogonal multiple access (NOMA) is currently one of the promising techniques for 6th generation (6G) wireless mobile networks, which can be combined with different technologies, such as cooperative communications and radio frequency (RF) power transfer. RF transmit energy over a medium has been seen an essential application systems. On other hand, due to mismatched components poor circuit fabrications, transceiver suffers from front-end effects in actual situations, in-phase quadrature-phase imbalance (IQI) degrade performance system. In this paper, we investigate harvest-then-cooperate assisted NOMA wireless-powered communication network (HTC-NOMA-WPCCN) practical constraints IQI imperfect successive interference cancellation (ISIC). We thereafter extend analysis multi-helper-user scheme improve our considered The linear non-linear EH are proposed analyze outage probability (OP), ergodic capacity (EC) throughput. discuss effect IQI, ISIC, image rejection ratio allocation on HTC-NOMA-WPCCN. Our theoretical validated by Monte Carlo simulations. simulation results demonstrate that ISIC significantly OP, EC throughput performances achieves better gain than EH. Furthermore, latter influenced more SIC imperfections, closely approach transmission. compare system UL without EH, clearly showed superiority Finally, changes ratio, WPCCN parameters impairments.
