LIS employs digitally controlled reflectors to enhance Signal-to-Interference plus Noise Ratio (SINR) and establish line of sight (LoS) connectivity in non-LoS environments, improving transmission security. Analytical expressions are derived to assess LIS performance metrics, including distribution parameters, bit error probability, and secrecy outage probability, considering the presence of eavesdroppers and environmental fading. The study highlights the potential of LIS technology to enhance the confidentiality and reliability of digital communication systems in next-generation networks.<\/jats:p>","DOI":"10.3390\/s24113332","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T09:04:25Z","timestamp":1716455065000},"page":"3332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Secrecy Analysis of a Mu-MIMO LIS-Aided Communication Systems under Nakagami-m Fading Channels"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9309-1735","authenticated-orcid":false,"given":"Ricardo Coelho","family":"Ferreira","sequence":"first","affiliation":[{"name":"Department of Communications, Faculty of Electrical and Computer Engineering, State University of Campinas (UNICAMP), Campinas 13083-970, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0517-1496","authenticated-orcid":false,"given":"Gustavo","family":"Fraidenraich","sequence":"additional","affiliation":[{"name":"Department of Communications, Faculty of Electrical and Computer Engineering, State University of Campinas (UNICAMP), Campinas 13083-970, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2167-7286","authenticated-orcid":false,"given":"Felipe A.
