More specifically, a doubly selective channel under high intercarrier interference (ICI) is considered. Current solutions involve complex detection and\/or reduced spectral efficiency receivers. This paper proposes the use of virtual carriers (VC) in an OFDM system with a low-complexity maximal ratio combining (MRC) detector to improve the bit error rate (BER) performance. The results show that VC provides diversity in received data, resulting in a \u22655 dB gain compared to previous OFDM systems with conventional linear\/nonlinear detectors used as a reference. The detector presented in this paper has linear complexity, making it a suitable solution for real-time V2V communication systems.<\/jats:p>","DOI":"10.3390\/s23156728","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T02:10:45Z","timestamp":1690510245000},"page":"6728","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Maximal Ratio Combining Detection in OFDM Systems with Virtual Carriers Over V2V Channels"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4039-1694","authenticated-orcid":false,"given":"J.
