FSO systems offer different technical and operational advantages such as higher bandwidth capacity, robustness to electromagnetic interference, a high degree of spatial confinement (bringing virtually unlimited reuse and inherent security), low power requirements, and unregulated spectrum. FSO communication can be deployed as an efficient solution for a wide range of applications such as military, last-mile access, fiber back-up, back-haul for wireless cellular networks, and disaster recovery. Although FSO systems have many appealing features, their performance can be hampered by degrading effects of atmospheric channel. In this talk, an overview on the FSO technology along with the advantages, challenges, and applications will be presented. At the end, some diversity techniques will be proposed which can improve the performance of FSO systems at the presence of the atmospheric fading.<\/p>\n\n\n\n<p><strong>Biography:<\/strong><br>\nSahar Molla Aghajanzadeh received the B.Sc. and the M.Sc. degree in electrical engineering from Sharif University of Technology, Tehran, Iran, in 2003 and 2006, respectively and the Ph.D. degree in electrical engineering from University of Waterloo, Waterloo, Canada. From 2012 to 2014, she was with Coding and Signal Transmission (CST) Laboratory, University of Waterloo as a postdoctoral fellow.  She is currently a research associate at Carleton University, Ottawa, Canada.  Her research interests include wireless communications in both optical and radio frequency domains with emphasis on free-space optic, channel coding, multiple-antenna systems, cooperative communication, and fading mitigation techniques in wireless channels.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CARLETON WIRELESS SEMINAR SERIES Date: Thursday, November 1, 1:30 pm Place: Carleton University, 4359 ME Title: FREE-SPACE OPTICAL COMMUNICATIONS: AN OVERVIEW Presenter: Dr. Sahar Molla Aghajanzadeh Research Associate Systems and Computer Engineering Carleton University Abstract: Free-space optic (FSO) is a line-of-sight technology which uses laser diodes to establish either a terrestrial or a non-terrestrial communication [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":1709,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[1],"tags":[],"class_list":["post-1705","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"acf":{"cu_post_thumbnail":""},"_links":{"self":[{"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/posts\/1705","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/comments?post=1705"}],"version-history":[{"count":3,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/posts\/1705\/revisions"}],"predecessor-version":[{"id":1710,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/posts\/1705\/revisions\/1710"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/media\/1709"}],"wp:attachment":[{"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/media?parent=1705"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/categories?post=1705"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/carleton.ca\/sce\/wp-json\/wp\/v2\/tags?post=1705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
