Four different receivers are studied in the scenarios described above, namely Equal Gain Combining (EGC), Maximum Ratio Combining (MRC), Zero Forcing (ZF), and Minimum Mean Squared Error (MMSE). The results of this article show that the use of LDPC codes leads to an improvement of performance by about 2 dB for a 4X25 LIS system and by 3 dB for a 4X225 LIS system, as compared to similar systems without LDPC codes. Moreover, for all simulations, the MMSE receiver achieves the best overall performance, while EGC performs the worst.<\/jats:p>","DOI":"10.3390\/app13084738","type":"journal-article","created":{"date-parts":[[2023,4,10]],"date-time":"2023-04-10T03:49:29Z","timestamp":1681098569000},"page":"4738","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["On the Performance of LDPC-Coded Large Intelligent Antenna System"],"prefix":"10.3390","volume":"13","author":[{"given":"Ali","family":"Gashtasbi","sequence":"first","affiliation":[{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5498-3220","authenticated-orcid":false,"given":"M\u00e1rio Marques","family":"da Silva","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":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"},{"name":"Ci2\u2014Centro de Investiga\u00e7\u00e3o em Cidades Inteligentes, 2300-313 Tomar, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8520-7267","authenticated-orcid":false,"given":"Rui","family":"Dinis","sequence":"additional","affiliation":[{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"},{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5106-239X","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Guerreiro","sequence":"additional","affiliation":[{"name":"Faculty of Sciences and Technology, Universidade Nova, 2829-516 Caparica, Portugal"},{"name":"Autonoma TechLab, 1169-023 Lisboa, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, 1049-001 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,10]]},"reference":[{"key":"ref_1","first-page":"165648","article-title":"Communication Modes with Large Intelligent Surfaces in the Near Field","volume":"9","author":"Decarli","year":"2021","journal-title":"IEEE Digit.
