In this paper, three low\u2010complexity antenna selection schemes are proposed that aim to enhance the physical layer security (PLS) of a multiple\u2010input multiple\u2010output (MIMO) NOMA system. The system is composed of a single transmitter, multiple legitimate users, and one eavesdropper, all equipped with multiple antennas. The first scheme maximizes the secrecy sum\u2010rate (SSR) of the system when the eavesdropper's channel state information (CSI) is known, whereas the second scheme maximizes SSR in the absence of CSI. In the third scheme, the emphasis shifts towards fairness, aiming to maximize the minimum secrecy rate across all users. Numerical results demonstrate that the performance of the first two proposed schemes is very close to that of the optimal case, albeit with much lower computational complexity. It is also observed that the third scheme enhances fairness by balancing users' secrecy rates, though with a moderate decrease in the overall secrecy sum\u2010rate.<\/jats:p>","DOI":"10.1002\/ett.70161","type":"journal-article","created":{"date-parts":[[2025,5,21]],"date-time":"2025-05-21T02:15:37Z","timestamp":1747793737000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Antenna Selection in MIMO\u2013NOMA Systems: A New Approach for Physical Layer Security Enhancement"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3400-6459","authenticated-orcid":false,"given":"Ehsan","family":"Alemzadeh","sequence":"first","affiliation":[{"name":"School of Electrical and Computer Engineering, College of Engineering University of Tehran  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8430-8229","authenticated-orcid":false,"given":"Amirmasoud","family":"Rabiei","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, College of Engineering University of Tehran  Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"1","volume-title":"Proceedings of the 2013 IEEE 77th Vehicular Technology Conference (VTC Spring)","author":"Saito Y.","year":"2013"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2015.7263349"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2018.1700080"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2015.2475746"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2017.2724420"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1109\/LWC.2015.2426709"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2016.2563462"},{"key":"e_1_2_7_9_1","first-page":"1","volume-title":"Proceedings of the 2016 IEEE 83rd Vehicular Technology Conference (VTC Spring)","author":"Liu X.","year":"2016"},{"key":"e_1_2_7_10_1","first-page":"1","volume-title":"Proceedings of the 2017 IEEE International Conference on Communications (ICC)","author":"Yu Y.","year":"2017"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2017.2750153"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2902331"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2019.0937"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/ett.4283"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2017.2737330"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICUFN.2018.8436960"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2019.2900090"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2003.821099"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2017.2711022"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2011.2158487"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/b98818"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1214\/aoms\/1177729893"},{"volume-title":"A Quantitative Measure of Fairness and Discrimination for Resource Allocation in Shared Computer Systems.
