One o f the most important subdivisions of OWC technology is the visible light communication (VLC) that uses visible light (VL) between the range 400 and 800 THz. VLC uses intensity modulation/direct detection (IM/DD). Hence the signals ought to be strictly real valued positive sequence. The fundamental modulation techniques such as on-off keying (OOK) and Pulse Position Modulation (PPM) are in accordance with existing constara current tight emitting diode (LED) drivers, however it comes with one drawback of having low spectral efficiency and restricted feasible data rates of VLC. Orthogonalfrequency-division multiplexing (OFDM) is one of the superior techniques that encode digital data on to multiple carrier frequencies and is widely known for providing high spectral efficiency. Despite of these advantages it comes with the disadvantage of high peak to average power ratio (PAPR) besides complicated Digital-to-Analog converter (DAC) and modification of LED drivers of VLC system being pre-requisite. Ln this paper, we present Delta-Sigma modulation (DSM) based OFDM which offers excellent robustness against noises and nonlinear distortions in VLC systems. The digital OFDM has been analyzed in terms of complementary cumulative distribution function (CCDF), error vector magnitude (EVM), bit error rate (BER) and received constellation diagram by means of MATLAB simulation to characterize the waveforms. Simulation results show that the DSM considerably enhances the system performance of digitized OFDM","PeriodicalId":380950,"journal":{"name":"2017 Global Wireless Summit (GWS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127479078","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}

In situations where the nature of source — destination link may not allow direct communication, the introduction of a relay can enhance the communication. Introduction of relays between sender and receiver nodes can improve D2D communication when the link suffers impairment. In this work we model the relay selection problem as stable matching market having two separate sets viz. a set of D2D pairs and a set of idle users that are available as relays. In constructing the preference lists of each set we have chosen separate criteria for populating the preference lists of members of the relay sets and members of the D2D set so that the relays maximize their incentive in the process of offering to relay information for D2D pairs. Channel uncertainties are also introduced in the source — relay links and relays — destination links. Our stable matching based algorithm performs better than a random selection algorithm, best source — relay link and best relay — destination link based selection algorithms.","PeriodicalId":380950,"journal":{"name":"2017 Global Wireless Summit (GWS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123163565","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}

New in the approach is the focus on the requirements of the vertical sectors. The salient characteristic of these sectors is that they are rapidly becoming open ecosystems built on top of common infrastructures. This requires a high degree of technological convergence among vertical industries empowering them with technical capacity and triggering the development of new, innovative products, applications and services. On the technology side, 5G is adopting new concepts and developments such as virtualization at all levels of the infrastructure enabling the 5G network infrastructure to become a key asset of the emerging common environment for technical and business innovation in the vertical sectors. In order to answer the questions \"How holistic and unified such an environment can be?\", and \"How an infrastructure can satisfy and reconcile competing requirements of the vertical sectors?\", we present the concept and approach of 5GINFTRE, a project that is tasked to build and operate an open, and extensible 5G NFV-based reference ecosystem of experimental facilities, laying down the foundations for a fully software controlled instantiation of virtual networks meeting the requirements of the vertical sectors.","PeriodicalId":380950,"journal":{"name":"2017 Global Wireless Summit (GWS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842643","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}
