In this sense, this work considers a wireless network that employs a dual-hop decode-and-forward (DF) relaying protocol, in which the receivers at the relay and at the base station (BS) use an antenna array. Moreover, it is considered that the received signals are combined at reception using equal-gain-combining (EGC). Recent works have enthusiastically employed the Weibull distribution so as to emulate the small-scale fading behavior in mmWave frequencies, which also motivates its use in the present work. For this scenario, exact and asymptotic expressions for the system\u2019s outage probability (OP) and average bit error probability (ABEP) are derived in closed form. Useful insights are gained from these expressions. More precisely, they illustrate how the system and fading parameters affect the performance of the DF-EGC system. Monte Carlo simulations corroborate the accuracy and validity of the derived expressions. Furthermore, the mean achievable rate of the considered system is also evaluated via simulations. Useful insights regarding the system performance are obtained from these numerical results.<\/jats:p>","DOI":"10.3390\/s23063174","type":"journal-article","created":{"date-parts":[[2023,3,17]],"date-time":"2023-03-17T02:59:26Z","timestamp":1679021966000},"page":"3174","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["On the Performance of Decode-and-Forward Equal-Gain-Combining Relay Systems over Weibull Fading Channels"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5200-3831","authenticated-orcid":false,"given":"Paula","family":"Tilleria Lucero","sequence":"first","affiliation":[{"name":"Faculty of Engineering and Applied Sciences (FICA), Telecommunications Engineering, Universidad de Las Am\u00e9ricas (UDLA), Quito 170503, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0529-8224","authenticated-orcid":false,"given":"Henry","family":"Carvajal Mora","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Applied Sciences (FICA), Telecommunications Engineering, Universidad de Las Am\u00e9ricas (UDLA), Quito 170503, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5232-7529","authenticated-orcid":false,"given":"Nathaly","family":"Orozco Garz\u00f3n","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Applied Sciences (FICA), Telecommunications Engineering, Universidad de Las Am\u00e9ricas (UDLA), Quito 170503, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3747-1511","authenticated-orcid":false,"given":"Fernando","family":"Almeida Garc\u00eda","sequence":"additional","affiliation":[{"name":"School of Electrical and Computer Engineering, University of Campinas (UNICAMP), Campinas 13083-852, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,16]]},"reference":[{"key":"ref_1","unstructured":"Proakis, J.
