    Optimization scheme for the SWIPT-NOMA opportunity cooperative system by Taoshen LI, Qianli NING, Zhe WANG

    Published 2020-08-01
    “…In order to improve the spectrum efficiency and performance of the simultaneous wireless information and power transfer (SWIPT) system,the non-orthogonal multiple access (NOMA) technology was introduced to construct the SWIPT-NOMA opportunistic relay system model.The fixed signal power allocation couldn’t adjust with other parameters of the system,and then affect the outage probability and resource utilization of the system.Therefore,a joint signal power and time allocation scheme was proposed to improve the system outage performance.In the proposed scheme,the expression of signal power distribution was obtained under the condition of satisfying the quality of service (QoS) rate of the node with poor channel state,and then the relation between the interruption probability and the time distribution of the system was deduced,the time allocation parameter was adjusted to affect the outage probability.The simulation results show that the constructed NOMA system has better outage performance than orthogonal multiple access (OMA) system,and the proposed joint signal power and time allocation outage scheme can effectively reduce the interruption probability of the system and improve the system performance.…”
