In particular, these advantages are used more effectively by the UAV when interacting with cellular networks such as 5G and beyond 5G. This system is defined as a cellular-UAV system [1]. In order to implement this system, reliable communication between base station and UAV is required. That is, well-designed CQI feedback mechanism is one of the essential technologies to be equipped. In traditional cellular network, the base station requires Channel Quality Indicator (CQI) feedback from users in order to determine a reasonable Modulation and Coding Scheme (MCS) in multicast system. However, traditional techniques also increase essential feedback as the group size increases and cause more signal overhead. This crucial problem can be equally applied to the cellular-UAV system. To cope with this problem, this paper proposes a new type of CQI feedback mechanism. The proposed schemes are expected not only to reduce signalling overhead but also to increase spectral efficiency, which is further demonstrated by the simulation results.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133830143","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}

A linear microstrip antenna array has been proposed to deploy the theory from Bat algorithm. The proposed array consists of 10 printed vertical antenna elements based on RO4003C substrate with the size of 160 x 450 x 1.524 mm3. When the array is fed by an ideal source, the simulated radiation pattern meets the requirement in term of null placement. A full design of the array for imposing a single null at the first side lobe has been proposed and investigated. Amplitude excitation weights are divided by a series feeding network. To improve the gain, a back reflector constructed on Fr-4 substrate with the size of 213 x 503 x 1.6 mm3has been used. The simulation results show that the first side lobe level can be suppressed to -40 dB at the frequency of 3.5 GHz while the maximum gain is 17.7 dBi. The simulated and measured reflection coefficients indicate that S1,1is equal -10 dB in the frequency range of 3.26-3.78 GHz. With these characteristics, the proposed antenna array is a good candidate for wireless systems in the C band.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126922650","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}

While forgery methods are increasingly more subtle that even human vision seems hard to recognize these manipulations, conventional algorithms, which try to detect tampering traces, often pre-define assumptions that limit the scope of problem. Therefore, such methods are unable to encounter forgery methods in general applications. In this paper, we propose a framework that utilizes Deep Learning techniques to detect tampered images. Concretely, the MobileNetV2 network in [21] is modified so that it can be consistent to the task of image forgery detection. We argue that by remaining spatial dimension of early layers, the model is likely to learn rich features in these layers, and then following layers are to abstract these rich features for making a decision whether an image is forged. Besides, we also conduct a comprehensive experiment to prove those arguments. Experimental results show that the architecture-modified network achieves a remarkable accuracy of 95.15%, which surpasses others relying on the original architecture by a large margin up to 12.09%.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132184313","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}

Its basic advantage is the possibility of being deployed on existing optical routes without the need to replace existing fibres or cables. The use of two optical fibre polarization axes allows the use of two independent transmission channels in a single optical fibre. The deployment options of Polarization Division Multiplexing can be evaluated using a tolerance field that can be obtained by measuring at the end of the optical path. This article discusses special measurement techniques and a new way of illustrating the Poincaré sphere's tolerance field., which allows evaluating the success of a Polarization Division Multiplexing technology at a glance. A detailed analysis of the tolerance field should simplify the idea of the activity of this type of multiplex and., for its clarity., it is also very suitable for study purposes. Unlike the transmission rate measurement., the measurement of the polarization multiplex tolerance field is a beneficial measurement showing the properties of the entire transmission system.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"59 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114048191","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}
