When the Photovoltaic string operates under partial shading conditions, the curve has several power peaks with only one Global Maximum Power Peak. The conventional maximum power point tracking strategies fail to deal with these attitudes. Many soft computing techniques are designed to deal with this issue, but the main challenges are to achieve that tracking with the quickest time, the minimum fluctuations, and the highest efficiency. In this paper, a modified Particle Swarm Optimization algorithm was proposed. It can exclude certain portions of the solution search area and redirects the newly created explorer particles into the promoted area until reach the Global max power point. The proposed method has been simulated for various power-against-voltage curves by using MATLAB / SIMULINK software. The results indicate that the proposed method outperforms the classical one with regards to the speed of Global Maximum Power Tracking with the lowest fluctuations and highest efficiency.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131221948","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}

Nowadays advanced guidance algorithms are used to cope with the increasing target's capabilities. Augmented proportional navigation guidance (APN) is one of the best guidance laws and the most efficient against highly maneuvering targets. Missile guidance loop has a complicated structure that comprises multiple minor loops that require a synchronized data collection from several sensors. That multitasking should be handled carefully to avoid any unrequired delays. So, implementation of these algorithms on a high-speed processor is a must to satisfy these requirements and to increase the missile's probability to hit the designated target. Field programmable gate array (FPGA) processors are generally recommended due to their high speed, low power consumption, and concurrent architecture design. In this research, APN guidance algorithm is designed using VHDL floating point approach and implemented on FPGA. Hardware-in-the-Loop (HIL) simulation is used to verify the designed algorithm and evaluate the overall performance of the designed model. A VHDL verifier toolbox in MATLAB® Simulink™ is used to link the FPGA processor with the missile model to construct the FPGA in the loop (FIL) simulation scheme. Simulation results from the FIL model are compared with simulation through different scenarios to evaluate the VHDL designed guidance law performance against highly maneuvering target.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115621760","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}

Until national laws allow unmanned aerial vehicles to fly independently, we will see large numbers of UAV swarms performing various tasks in the intelligent cities, including package delivery, facility management, event filming, monitoring and tracking. 5G/B5G mobile networks will benefit the UAV environment, and it can be used to enhance UAV communications in a variety of ways. UAVs' features of versatile mobility in 3D space, as well as autonomous operations and intelligent positioning, accommodate a wide range of wireless technologies and applications. This paper is meant to detail how 5G/B5G mobile systems and UAV technology merge to offer both enhanced aerial mobility and increased data capabilities for mobile users (UE). Cellularly linked UAVs play the role of cellular flying consumers, and are referred to as UAVs with a direct connection to consumers (a.k.a. UAV-UE, drone-UE, 5G-connected drone, or aerial user). This project's focus is to assemble an in-depth task analysis along with essential technical advancements in 5G/B5G and on-going field trial and prototyping work on cell-based UAVs. This report details recent developments within the 3GPP organisation and presents social and economic issues that must be taken into consideration before a successful introduction of this potentially useful technology. Accessible issues are already present and pave the way for future opportunities.","PeriodicalId":321025,"journal":{"name":"2021 International Telecommunications Conference (ITC-Egypt)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116490082","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}
