Although FSO systems are based on a cheap, safe and efficient technology, there are many degrading effects that should be taken into account. In particular, long and fast links suffer from many existing effects, acting cumulatively, resulting in a not negligible deterioration of both performance and availability, as their length or bit rate increases. And that is because of the FSO pulse propagation through dispersive atmospheric channels, while short timed pulses are prone to be misdetected in adjacent time slots at the receiver, leading to disturbances in the bit stream, consequently. This work includes the estimation of FSO link performance, focusing on both the group velocity dispersion and the time jitter effects, calculated in terms of both probability of fade and outage probability, using closed form mathematical expressions. Then, interesting numerical results and conclusions are presented for typical FSO links' parameters.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130163415","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}

Different types of optical interconnects for inter/intra chip links are under development. Electro-optical modulators (EOMs) are one of key elements of optical links. Transmission-type EOM for chip-to-chip optical interconnection is analysed by the method of single expression. Transmission properties of Fabry-Perot resonant type modulator consisting of electro-optical material embedded between Si/SiO2 distributed Bragg reflectors (DBRs) are analysed. From four possible types of DBRs the suitable structure has been chosen. Two semitransparent conducting electrodes for applying electrical signal to electro-optical material are parts of the nano-layered structure and are included in the electromagnetic model. As an external light source, a conventional laser diode of wavelength 1.55 $mu m$ is taken. Efficiency of optical wave intensity modulation is analysed by means of influence of electro-optical material's permittivity change (under applied voltage) on resonator's maximal transmission peak shift. For the electro-optical material LiNbO3 of thickness about 1 mm the suitable resonance peak shift is obtained.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131719425","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 this work, we propose the concept of an ISAC system based solely on visible light that performs the task of sensing the rotational position of a cylinder mounted on a servomotor with an average absolute deviation of ~!1.2° and the task of forwarding the commands to reach a defined rotational position. The feasibility of the implemented ISAC system is verified by experimental results that demonstrate the applicability of such a visible light based ISAC systems in the era of $6mathbf{G}$. Furthermore, we show a simple and effective method to compensate the impacts of additional ambient light on the operation performance.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132916064","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}

However, the performance of THz wireless systems is subject to free space path loss, signal attenuation due to humid air, atmospheric turbulence and pointing errors between transmitter and receiver terminals. Thus, in this work we first introduce the stochastic impact of generalized PEs with nonzero boresight in the THz area, while atmospheric turbulence is modeled through the suitable gamma gamma distribution. Considering also the deterministic impact of free space path loss and signal attenuation, an outage probability analysis is performed for a typical line of sight THz link. In this context, novel closed form expressions are derived. Their analytical results demonstrate the joint influence of these effects on THz signal transmissions, while simulation results validate the accuracy of our analysis.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"184 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124918575","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}

One interesting use-case is life presence detection, which is finding living bodies - human or animal - in an otherwise static environment. An example is the localization of humans under debris (e.g. after earthquakes). But also, the automotive sector has found use-cases for UWB radars: monitoring of the driver's vital functions or reminding the driver of children or animals left inside, when the user locks the car and walks away. In particular, it is quite a challenge to detect infants in cars within a short period of time. Compared to adults not a lot of measurement data is available for infants and there are also no appropriate models for numerical simulation.
