Investigate the Dominating Factor of Hybrid SWIPT Protocol by Performance Analysis of the Far User of Hybrid SWIPT based CNOMA Downlink Transmission

Cooperative Non-Orthogonal Multiple Access (CNOMA) is a superior solution to increase the reliability of the far user. This technique treated the near user as relay for the far user or cell edge user which required significant power consumption. Hence hybrid simultaneous wireless information and power transfer (HS) protocol is considered with CNOMA downlink transmission to energize the relay operation without draining the battery of near user. Transmit antenna selection scheme is also integrated with the considered system. So this paper investigates the dominant factor among the fraction of block time for energy harvesting or power-splitting ratio in case of outage probabilities and channel capacity for the far user of the considered system with Single Input Single Output (SISO) scheme and Multiple Input Single Output (MISO) scheme as well. The simulation results of the channel capacities of the far user are compared with analytical results respectively.
