This article focuses on LIS systems, analysing the impact of the use of a whole LIS system or a subset of an antenna array. We analyse an LIS system associated with a single carrier with frequency domain equalization (SC-FDE), and with different receiver types of varying complexities. Because it is a function of the number of antennas, the computational complexity decreases when antenna elements that are closer to the user equipment are used instead of the whole LIS. Moreover, with a partial LIS, a reduction of energy consumption is achieved, and mitigation of the interference levels is obtained, allowing a performance very close to that obtained with the whole LIS system.<\/jats:p>","DOI":"10.3390\/electronics13061035","type":"journal-article","created":{"date-parts":[[2024,3,11]],"date-time":"2024-03-11T04:51:12Z","timestamp":1710132672000},"page":"1035","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["On the Performance of Partial LIS for 6G Systems"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5498-3220","authenticated-orcid":false,"given":"M\u00e1rio","family":"Marques da Silva","sequence":"first","affiliation":[{"name":"Department of Engineering and Computer Sciences, Universidade Aut\u00f3noma de Lisboa, 1169-023 Lisboa, Portugal"},{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"},{"name":"Ci2\u2014Centro de Investiga\u00e7\u00e3o em Cidades Inteligentes, 2300-313 Tomar, Portugal"}]},{"given":"Ali","family":"Gashtasbi","sequence":"additional","affiliation":[{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8520-7267","authenticated-orcid":false,"given":"Rui","family":"Dinis","sequence":"additional","affiliation":[{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"},{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"}]},{"given":"Gelson","family":"Pembele","sequence":"additional","affiliation":[{"name":"Department of Engineering and Computer Sciences, Universidade Aut\u00f3noma de Lisboa, 1169-023 Lisboa, Portugal"},{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4246-3957","authenticated-orcid":false,"given":"Am\u00e9rico","family":"Correia","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"},{"name":"Department of Information Science and Technology, ISCTE-Instituto Universit\u00e1rio de Lisboa, 1649-026 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5106-239X","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Guerreiro","sequence":"additional","affiliation":[{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"},{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4023","DOI":"10.1109\/LRA.2018.2860628","article-title":"Artificial Intelligence for Long-Term Robot Autonomy: A Survey","volume":"3","author":"Kunze","year":"2018","journal-title":"IEEE Robot.
