Drone communication with Non-Orthogonal Multiple Access (NOMA) can be a solution for these demands entirely. Drones can be used as aerial base stations with their high mobility, and better coverage provides communication whenever and wherever it’s required. Also, NOMA has several advantages over conventional Orthogonal Multiple Access (OMA) techniques. These advantages are spectral efficiency, low latency, and better sum rate. These advantages make the NOMA perfect solution for today’s communication demands in 5G and beyond. In this paper, the performance of NOMA in drone communication is investigated. Individually, the capacity and fairness index’s changes in the considered system with different power allocation (PA) schemes have been examined.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"3 1","pages":"1070-1074"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79169176","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}

The original image obtained was processed in two ways. To start with, images were divided into overlapping blocks and gray level co-occurrence matrix (GLCM) from these blocks was generated and texture features were extracted using these GLCMs. Then, blocks containing or not containing watermelon were classified by employing a linear classifier. As a result of this study, the accuracy of watermelon classification was obtained as 86.46%. Second, k-means clustering of the original image was performed. Following this, groups having the highest blue value at its center were chosen. Finally, first and second results were combined with logical and operator. It was derived from this study that the method may be useful for detecting watermelons in field images obtained via UAV for counting and yield estimation.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"67 1","pages":"619-622"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83723434","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}

The proposed NARMA controller comprises of a linear controller and an LFL block. The LFL block concatenated with the nonlinear plant constitutes a linear closed loop system so that linear control is applicable. An online learning algorithm is used for the data-dependent identification of the linearized plant and then for the data-dependent design of the linear part of the NARMA controller. The identification of the linearized plant starts with the determination of the LFL block in a supervised way by exploiting the input and the corresponding state data obtained from the nonlinear plant. The linearized plant is then identified as an ARMA model by the data generated with the combination of the already learned LFL block and the nonlinear plant. Robustness of the linearized system model is obtained by employing the ε-insensitive loss function ℓ1, ε(•,•) as the identification error of the linearized system. The Schur stability of the overall closed loop system is ensured by the linear inequality constraints imposed in the minimization of the ℓ1, ε(•,•) tracking error for determining the linear controller parameters. The proposed LFL based NARMA controller is tested on ROTPEN model and its performance is compared with the Proportional-Derivative controller and Hammerstein based NARMA adaptive controller.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"68 1","pages":"795-799"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80632728","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}

The less utilized devices mean, the lower the cost of implementation, size of the system, required installation area, control complexity, and also higher reliability. The proposed structure is modular and can operate in two modes (symmetric and asymmetric), which are discussed in this paper. To express the worthiness of the presented structure, a comparison with the conventional cascade H-bridge MLI is presented.
