Title

ENHANCING THE SECURITY OF MISO-NOMA SWIPT SYSTEM USING COOPERATIVE JAMMING SCHEME

Abstract

The new era of wireless communication systems requires sophisticated communication techniques that can attain high spectral efficiency (SE) and give massive connectivity between the users. So, Non-orthogonal multiple access (NOMA) and simultaneously wireless information as well as power transfer (SWIPT) are two favorable methods to enhance spectral efficiency and also energy efficiency in CR networks. Here, an Artificial noise-aided beamforming design problems under both perfect and imperfect channel State information (CSI) are studied to enhance the security of a multiple-input single-output NOMA SWIPT system where a realistic non-linear ER model is used. So in order to enhance the security of the primary network, an artificial noise-aided cooperative jamming scheme for MISO-NOMA SWIPT sytem is proposed. The Artificial noise aided beamforming design problems are studied subject to the practical secrecy rate and energy harvesting constraints. Here, the transmission power minimization problems are formulated under the both perfect channel state information (CSI) and the imperfect CSI model. To resolve these non-convex problems, pair of algorithms semi definite relaxation (SDR) and a cost function algorithms are proposed. Our simulation results shown that the proposed scheme flourishes in establishing secure communication and it is envisioned that applying NOMA in CR networks is capable of significantly improving the Spectral efficiency and user connectivity. Finally, the performance of our proposed method is improved than that obtained by OMA.
