In this context, this work introduces a novel VLC receiver architecture that integrates a field-of-view (FoV) adaptation mechanism in accordance with the optical noise generated by the sun. In order to demonstrate the benefits of this concept, a VLC prototype was experimentally tested in an infrastructure-to-vehicle (I2V) VLC configuration, which uses an LED traffic light as the transmitter. At the receiver side, an automatic FoV adaptation mechanism was designed based on a mechanical iris placed in front of a photodetector. Adjustments were made based on the values recorded by a multi-angle light sensor, built with an array of IR photodiodes covering an elevation from 0\u00b0 to 30\u00b0 and an azimuth from \u221230\u00b0 to 30\u00b0. Depending on the incidence of solar light, the mechanical iris can adjust the FoV from \u00b11\u00b0 to \u00b122\u00b0, taking into account both the light irradiance and the sun\u2019s position relative to the VLC receiver. For experimental testing, two identical VLC receivers were used: one with an automatic FoV adjustment, and the other with a \u00b122\u00b0 fixed FoV. The test results performed at a distance of 50 m, in the presence of solar irradiance reaching up to 67,000 \u00b5W\/cm2, showed that the receiver with a fixed FoV saturated and lost the communication link most of the time, whereas the receiver with an adjustable FoV maintained an active link throughout the entire period, with a bit error rate (BER) of less than 10\u22127.<\/jats:p>","DOI":"10.3390\/s24092814","type":"journal-article","created":{"date-parts":[[2024,4,29]],"date-time":"2024-04-29T08:49:24Z","timestamp":1714380564000},"page":"2814","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Driving toward Connectivity: Vehicular Visible Light Communications Receiver with Adaptive Field of View for Enhanced Noise Resilience and Mobility"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2200-6775","authenticated-orcid":false,"given":"Alin-Mihai","family":"C\u0103ilean","sequence":"first","affiliation":[{"name":"Integrated Center for Research, Development and Innovation in Advanced Materials, Nanotechnologies and Distributed Systems for Fabrication and Control, Stefan cel Mare University of Suceava, 720229 Suceava, Romania"},{"name":"Department of Computers, Electronics and Automation, Stefan cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4007-9812","authenticated-orcid":false,"given":"Sebastian-Andrei","family":"Av\u0103t\u0103m\u0103ni\u021bei","sequence":"additional","affiliation":[{"name":"Integrated Center for Research, Development and Innovation in Advanced Materials, Nanotechnologies and Distributed Systems for Fabrication and Control, Stefan cel Mare University of Suceava, 720229 Suceava, Romania"},{"name":"East European Border Scientific and Technological Park, 725500 Siret, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4267-2919","authenticated-orcid":false,"given":"C\u0103t\u0103lin","family":"Beguni","sequence":"additional","affiliation":[{"name":"Integrated Center for Research, Development and Innovation in Advanced Materials, Nanotechnologies and Distributed Systems for Fabrication and Control, Stefan cel Mare University of Suceava, 720229 Suceava, Romania"},{"name":"Department of Computers, Electronics and Automation, Stefan cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3204","DOI":"10.1109\/COMST.2019.2913348","article-title":"Visible Light Communication: Concepts, Applications and Challenges","volume":"21","author":"Matheus","year":"2019","journal-title":"IEEE Commun.
