The size of the device is here imposed by both the high bit rate of the link under study and the necessity to compensate for free-space power attenuation. Mini compound parabolic prototypes are designed and fabricated in PMMA using a 3D micro-milling machine. The device are then characterized through static and dynamic tests.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127833435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preliminary results drawn from the analysis of moderate radiation fogs in an urban area show that the time series of visibility and attenuation are well correlated when data are low-pass filtered (a simple moving average window with duration from 1-min to 5-min was applied). Moreover, the analysis evidences rather different and well defined statistical properties for the above slowly varying component and the fast signal fluctuations. If confirmed on a larger database, these features would represent an important step towards the development of a synthetic time series generator of fog events.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115573514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Popoola","doi":"10.1109/IWOW.2013.6777797","DOIUrl":"https://doi.org/10.1109/IWOW.2013.6777797","url":null,"abstract":"In this paper an optical wireless communication system that uses spatial modulation (SM), a concept of encoding information on the spatial location in space of an optical source to increase data rate, is discussed with the view to highlighting its merits and limitations. The SM technique represents a low complexity, alternative method of increasing the number of bits transmitted per symbol. The technique depends on the natural disparity in the channel parameters of optical sources that occupy different positions in space. As a result, the error performance of an SM technique is heavily influenced by the receiver location with respect to the optical sources as well as how similar or dissimilar the channel gain values are. Simulation results for three transmitting LED sources in a room show that for a mobile receiver to ensure wireless communication at a symbol error rate of 10-6, up to 109 dB of signal-to-noise ratio (SNR) is required. This high SNR requirement will undoubtedly impose limitations on the system particularly when the receiver is mobile and the available optical power is limited.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115195180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
