Cellular Communication Propagation at Drone around Building Environment with Single Knife Edge at 10 GHz

The drone communication systems used a cellular network for controlling a drone from a long distance. That communication propagations between drone and base station were analyzed. The drone moved at the track around building environment. That environment used variations in building height. The communication propagation around building environment caused diffraction mechanism. Single knife edge method is used for that diffraction mechanism. The frequency of communication used 10 GHz. That frequency was influenced by atmospheric attenuation. This research was using some variations such as height of drone track location, transmitter power, and AMC (Adaptive Modulation Coding). MCS (Modulation Coding Scheme) was used AMC such as QPSK, 16 QAM, and 64 QAM. Some result was obtained at this research consist of LOS and NLOS distance, SNR, MCS probability, and percentage of drone coverage. NLOS propagation was caused by building height. The SNR value become increase when higher at drone position, such as drone was moving at 20 meters with height of flying drone 80 m and transmitter power 30 dBm obtained SNR 38.21 dBm. That SNR is affected AMC, so a higher SNR value increases AMC. The drone’s coverage 100%, with a height of flying drone 80 meters and transmitter power of 30 dBm. That condition showed more increasing coverage percentage than 64.8% for height of flying drone 20 meters and transmitter power 30 dBm. That result showed that more drone height increased of coverage percentage, probability modulation, and SNR value.The drone communication systems used a cellular network for controlling a drone from a long distance.

An Asset Pricing Perspective on the Design of Cryptocurrencies

Hinsichtlich ihrer Ausgestaltung sind Kryptowährungen eine äußerst heterogene Assetklasse. Die vorliegende Dissertation analysiert Kryptowährungen aus der Perspektive des Asset Pricings unter expliziter Berücksichtigung dieser vielfältigen Designunterschiede. Dabei eröffnet sie einen eigenen, neuen Blick auf die Bewertung, die Preisvolatilitäten und die Risiko-Ertrags-Profile von Kryptowährungen. In ihrem ersten Teil entwickelt die Arbeit eine neue Taxonomie. Diese ermöglicht, die Ausgestaltung verschiedener Kryptowährungen anhand von sechs übergeordneten Klassen zu kategorisieren. Auf Grundlage der Taxonomie und unter Verwendung händisch erfasster Daten von 79 Kryptowährungen unter-sucht Kapitel 2 bzw. Kapitel 3 die Auswirkungen der erfassten Designkomponenten auf die Marktkapitalisierung bzw. die Preisvolatilität der jeweiligen Kryptowährungen. Unter anderem wird dabei gezeigt, dass die Aussicht auf regulatorische Anerkennung die Marktkapitalisierung positiv beeinflusst, wohingegen ein geringer Innovationsgrad negative Auswirkungen hat. Die Ergebnisse der Analysen sind für Investoren, Regulierungsbehörden und Entwickler von entscheidender Bedeutung, da sie den Zusammenhang zwischen Designvariablen und Marktperformance aufzeigen und so zu einer fundierten Entscheidungsfindung und Politikformulierung beitragen. Ein essentieller Baustein von Kryptowährungen sind die sogenannten Konsensusprotokolle. Obwohl diverse Verfahren eine dezentrale Einigung über die Datenpunkte im zugrundeliegenden, verteilten System ermöglichen, dominieren die beiden Verfahren Proof-of-Work (PoW) und Proof-of-Stake (PoS) das Kryptowährungsuniversum. Während PoW, das unter anderem im Bitcoin-Kosmos verwendet wird, mit einem exzessiven Ressourcenverbrauch assoziiert wird, gewährleistet PoS die Integrität des zugrundeliegenden Netzwerks bei weitaus geringerem Energieverbrauch. Der PoS-Mechanismus beruht auf Agenten, welche ihre Coins über spezielle Transaktionen einfrieren (Staking) und dadurch anteilig autorisiert werden, Transaktionen zu validieren. Dies ist einhergehend mit einer Entlohnung in Form neu geschaffener Coins. Da die eingefrorenen Coins ihre Transaktionsfähigkeit verlieren, ist Staking mit Opportunitätskosten verbunden. Der zweite Teil der Dissertation (Kapitel 4) entwickelt ein ökonomisches Modell, welches dieses Opportunitätskostenproblem in den Mittelpunkt rückt und zeigt, dass diese Struktur eine erhöhte Fragilität, d.h. ein erhöhtes Risiko für Zusammenbrüche des Netzwerks, hervorrufen kann. Dabei bestimmen einige Designkomponenten entscheidend über das Ausmaß der Fragilität. Basierend auf einem Tagsystem, welches von coinmarketcap.com unterhalten wird und auf deren Website verfügbar ist, wird im dritten Teil der Arbeit (Kapitel 5) der gesamte Querschnitt des Kryptowährungsmarkts anhand selektierter Designkomponenten klassifiziert. Mithilfe einer IPCA nach Kelly u.a. (2019) und der methodischen Idee von Müller u. a. (2020) können die Risikoprämien dieser Designkomponenten identifiziert und analysiert werden. Die Arbeit zeigt, dass das im zweiten Teil herausgearbeitete Opportunitätskostenproblem und die damit einhergehende gestiegene Fragilität durch eine Prämie von PoS gegenüber PoW während der Jahre 2019 und 2020 kompensiert wird. Seit Dezember 2021 übersteigt der erwartete Ertrag von PoW-basierten Kryptowährungen den von PoS-basierten Kryptowährungen. Es wird gezeigt, dass diese Beobachtung mit Bedenken in Bezug auf den Klimawandel und mit Energiepreisen korreliert. Die ergänzende Analyse der Risikoprämien von Coins vs. Tokens, Privacy vs. Non-Privacy und Smart Contract vs. Non-Smart Contract runden diese Dissertation ab, die einen Blickwinkel aus der Asset Pricing Perspektive auf Kryptowährungen und deren Design eröffnet

Determination of MS Location through Building Using AoA Method of Frequency 47 GHz

This research discusses the determination of mobile station (MS) location of the uplink communication system. The location determination mobile station is based on the angle-of-arrival (AoA) method. The communication propagation is influenced by building environment. The building environment was modeled with diffraction method. Several diffraction methods were used such as single knife edge, and multiple knife edge method. The communication frequency used was 47 GHz. The analysis used percentage value at coverage area and comparison of error percent values between two method to determine mobile station location. The percentage of the communication coverage area obtained was 71.4% or of 255 from 300 nodes. The comparison methods used for mobile station location determination were the selection of the best SNR and localization technique. The error percentage value based on the selection of the best SNR method is 0.95%. The error percentage value based on localization technique method is 0.78%
