It consists of exploiting the vehicular wireless channel characteristics in the form of Channel State Information (CSI) in the receiver side of a connected vehicle in order to identify the environment type in which the vehicle is driving, without any need to implement specific sensors such as cameras or radars. We consider environment identification as a classification problem, and propose a new convolutional neural network (CNN) architecture to deal with it. The estimated CSI is used as the input feature to train the model. To perform the identification process, the model is targeted for implementation in an autonomous vehicle connected to a vehicular network (VN). The proposed model is extensively evaluated, showing that it can reliably recognize the surrounding environment with high accuracy (96.48%). Our model is compared to related approaches and state-of-the-art classification architectures. The experiments show that our proposed model yields favorable performance compared to all other considered methods.<\/jats:p>","DOI":"10.3390\/s22229018","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T05:18:57Z","timestamp":1669094337000},"page":"9018","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Vehicular Environment Identification Based on Channel State Information and Deep Learning"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5991-8997","authenticated-orcid":false,"given":"Soheyb","family":"Ribouh","sequence":"first","affiliation":[{"name":"Normandie Universit\u00e9 Rouen, LITIS (Laboratoire d\u2019Informatique, de Traitement de l\u2019Information et des Syst\u00e8mes), Av. de l\u2019Universit\u00e9 le Madrillet, 76801 Saint Etienne du Rouvray, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6688-2945","authenticated-orcid":false,"given":"Rahmad","family":"Sadli","sequence":"additional","affiliation":[{"name":"D\u00e9partement d\u2019Opto-Acousto-\u00c9lectronique, DOAE, Institut d\u2019\u00c9lectronique de Micro\u00e9lectronique et de Nanotechnologie, IEMN, Universit\u00e9 Polytechnique Hauts-de-France, UMR 8520, 59300 Valenciennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yassin","family":"Elhillali","sequence":"additional","affiliation":[{"name":"D\u00e9partement d\u2019Opto-Acousto-\u00c9lectronique, DOAE, Institut d\u2019\u00c9lectronique de Micro\u00e9lectronique et de Nanotechnologie, IEMN, Universit\u00e9 Polytechnique Hauts-de-France, UMR 8520, 59300 Valenciennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atika","family":"Rivenq","sequence":"additional","affiliation":[{"name":"D\u00e9partement d\u2019Opto-Acousto-\u00c9lectronique, DOAE, Institut d\u2019\u00c9lectronique de Micro\u00e9lectronique et de Nanotechnologie, IEMN, Universit\u00e9 Polytechnique Hauts-de-France, UMR 8520, 59300 Valenciennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9092-735X","authenticated-orcid":false,"given":"Abdenour","family":"Hadid","sequence":"additional","affiliation":[{"name":"Sorbonne Center for Artificial Intelligence, Sorbonne University Abu Dhabi, Abu Dhabi P.O.
