Free space optical communication is deployed to provide a reference for jamming cancellation. The mixed signal is processed and separated with photonic signal processing method to achieve large bandwidth. As an analog signal processing method, the cancellation system introduces zero latency. The radio frequency signals are modulated on optical carriers to achieve wideband and unanimous frequency response. With wideband and zero latency, the system meets the key requirements of high speed and real-time communications in transportation systems.<\/jats:p>","DOI":"10.3390\/s21041136","type":"journal-article","created":{"date-parts":[[2021,2,7]],"date-time":"2021-02-07T14:07:40Z","timestamp":1612706860000},"page":"1136","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Wideband Anti-Jamming Based on Free Space Optical Communication and Photonic Signal Processing"],"prefix":"10.3390","volume":"21","author":[{"given":"Ben","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Rowan University, 201 Mullica Hill Rd., Glassboro, NJ 08028, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0530-8640","authenticated-orcid":false,"given":"Yang","family":"Qi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Rowan University, 201 Mullica Hill Rd., Glassboro, NJ 08028, USA"}]},{"given":"Chenxi","family":"Qiu","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Rowan University, 201 Mullica Hill Rd., Glassboro, NJ 08028, USA"}]},{"given":"Ying","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Rowan University, 201 Mullica Hill Rd., Glassboro, NJ 08028, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1109\/MCOM.2017.1600238CM","article-title":"UAV-Enabled Intelligent Transportation Systems for the Smart City: Applications and Challenges","volume":"55","author":"Menouar","year":"2017","journal-title":"IEEE Commun.
