In doubly dispersive channels, Inter-Carrier Interference (ICI) degrades subcarrier orthogonality, rendering conventional equalization ineffective. Current ICI mitigation techniques face a trade-off between Bit-Error Rate (BER) performance and computational complexity, limiting their applicability in dynamic vehicular scenarios. To address this issue, a low-complexity MobileNetV3-based receiver is proposed, incorporating a signal-model-driven preprocessing stage that compensates for Doppler-induced phase distortions responsible for ICI. Simulation results show that the proposed receiver improves BER performance compared to conventional equalizers and recent neural-based schemes in the low-SNR regime (below 15 dB) while maintaining computational complexity close to linear least-squares detection.<\/jats:p>","DOI":"10.3390\/a19030210","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T09:00:37Z","timestamp":1773219637000},"page":"210","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficient Deep Learning-Based M-PSK Detection for OFDM V2V Systems Using MobileNetV3"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7952-4449","authenticated-orcid":false,"given":"Luis E.","family":"Tonix-Gleason","sequence":"first","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Panamericana, \u00c1lvaro del Portillo 49, Zapopan 45010, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4039-1694","authenticated-orcid":false,"given":"Jos\u00e9 A.","family":"Del-Puerto-Flores","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Panamericana, \u00c1lvaro del Portillo 49, Zapopan 45010, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9481-2058","authenticated-orcid":false,"given":"Fernando","family":"Pe\u00f1a-Campos","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Communications Section, Cinvestav, Guadalajara 45019, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7190-6641","authenticated-orcid":false,"given":"Dunstano","family":"del Puerto-Flores","sequence":"additional","affiliation":[{"name":"Department of Mechanical-Electrical Engineering, CUCEI, University of Guadalajara, Guadalajara 44430, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7844-3261","authenticated-orcid":false,"given":"Juan-Carlos","family":"L\u00f3pez-Pimentel","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Panamericana, \u00c1lvaro del Portillo 49, Zapopan 45010, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0272-3275","authenticated-orcid":false,"given":"Carolina","family":"Del-Valle-Soto","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad Panamericana, \u00c1lvaro del Portillo 49, Zapopan 45010, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7760-3876","authenticated-orcid":false,"given":"Luis Ren\u00e9","family":"Vela-Garcia","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Communications Section, Cinvestav, Guadalajara 45019, Mexico"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,11]]},"reference":[{"key":"ref_1","unstructured":"(2026).
