Up to now, the visible light wireless data center links are still limited to the conventional Lambertian beam paradigm. The potential coverage gain relevant to the optical beam space is waiting for sufficient investigation. For addressing this issue, in this paper, the dynamic optical beam based WDC coverage enhancement scheme is introduced, and for each transmitter, the best candidate asymmetrical optical beam is selected to load the data signal. Numerical evaluation shows that, compared with the conventional static beam configuration, up to 6.76 dB peak signal to noise ratio (SNR) gain and 4.46 dB average SNR gain could be provided by the proposed dynamic beam scheme. Moreover, this SNR dynamic range is reduced to 36.65 dB while the counterpart of the static non-Lambertian beam configuration is up to 44.78 dB.<\/jats:p>","DOI":"10.3233\/faia210439","type":"book-chapter","created":{"date-parts":[[2021,12,29]],"date-time":"2021-12-29T10:33:55Z","timestamp":1640774035000},"source":"Crossref","is-referenced-by-count":0,"title":["Visible Light Wireless Data Center Links with Distinct Beam Configurations"],"prefix":"10.3233","author":[{"given":"Jupeng","family":"Ding","sequence":"first","affiliation":[{"name":"Key Laboratory of Signal Detection and Processing in Xinjiang Uygur Autonomous Region, School of Information Science and Engineering Xinjiang University, Urumqi, China"}]},{"given":"Chih-Lin","family":"I","sequence":"additional","affiliation":[{"name":"China Mobile Research Institute, Beijing, China"}]},{"given":"Lili","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Ludong University, Yantai, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Proceedings of CECNet 2021"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA210439","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,12,29]],"date-time":"2021-12-29T10:33:57Z","timestamp":1640774037000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA210439"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,12,22]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia210439","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,12,22]]}}}
