Communication is performed among base station (BS) and paired users in arbitrary number of clusters. The channels are described by Fischer-Snedecor $(boldsymbol{F})$ fading model. The outage probability and sum data rate are defined for power-domain NOMA using data rate-based power allocation procedure. Comparison of two pairing schemes, D-NLUPA and High-Low, is done in terms of aforementioned metrics. Numerical results also show the influence of fading depth and shadowing sharpness; user locations, and the number of users in the cell.","PeriodicalId":278683,"journal":{"name":"2023 58th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130565266","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}

There are and will be a high increase of installed PV capacity in the power system that will have impact on imbalances and frequency regulation reserves. The methodology for the assessment of RES impact on frequency regulation reserves is based on the data available for the authors for the years 2015 and 2016, about hourly deviations (imbalances) of PV, WPP and load.

The applications are very versatile, like driver monitoring, autonomous driving, industry applications related to non-destructive material testing, food control and improving efficiency in agriculture. The future 6G standards will further extend the use of mm-wave bands for increasing data rates and incorporating sensing functionality. From semiconductor technology and design perspective significant progress has been made to gain speed, reliability and design flows that guarantee first-time right mm-wave circuits.

The models - SlowFast, X3D and MViT are evaluated using accuracy top-1, and the results are identifying the best-performing combinations of dataset and model.
