The dielectric resonator is excited electrically by a quadrature-fed loop antenna having a capacitive gap to control its input impedance matching. The electromagnetic energy couples from the loop antenna to the rectangular dielectric placed on top of it. A phase inverter is inserted in one of the loop antenna arms that contributes to dual resonance behaviour of the dielectric resonator by introducing an approximate phase shift of 90 degree in operating bands. The proposed antenna operates at 3.34 GHz and 4.76 GHz. The antenna exhibits broadside radiation, with maximum radiation occurring at the top, with directivity of 7.37 dBi and 7.13 dBi in operating bands, respectively. The proposed antenna is suitable for using in wireless communication systems.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"40 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":"125797204","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}

Results expose that the relay's location, energy scavenging time, message recovering time, and power division for energy scavenging and message recovering dramatically impact the SOP of the cooperative communications in ESCRNs. Moreover, results infer that the SOP is constant either in energy scavenging non-cognitive networks (ES-nonCRNs) or in ESCRNs with infinite power transmitters.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"34 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":"122664293","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}

However, inter-code interference (ICI) due to various factors decreases the implicit time diversity effect. This paper addresses reducing of ICI caused by the periodic blockage in WHCDM. As ICI reduction methods, the explicit time diversity with maximal ratio combining (MRC), zero-forcing (ZF), and minimum mean square error (MMSE) are investigated. The computer simulation shows that the three methods are effective for reducing the ICI. We also confirm that MMSE is superior to MRC and ZF in terms of BER performance.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"8 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":"128607988","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}

Traditional image upscaling techniques have low computational complexity and applicable for real-time processing, but reconstructed image often contains artifacts and undesirable visual effect. The relationship between image interpolation and super-resolution leads our assumption that the interpolated image can be further optimized and may be considered as a part of super-resolution algorithm. In this paper, we propose a new image super-resolution method to combine fast image interpolation with iterative back-projection. This method does not require any external pre-trained datasets and has low computation time while the quality of the reconstructed image can be measured up to the high programming complexity methods such as the dictionary and deep convolutional neural networks.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"54 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":"123725857","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}

With the spreading LEDs, VLC has been gaining attention as an effective communication means. Propagation medium of VLC is tremendously higher frequency electromagnetic waves than terahertz and hence VLC has superiority in terms of communication directivity and security. Under the use of VLC-OFDM, joint application of IDMA and spreading codes has been previously proposed for uplink multiple access scheme which can exhibit superior multiple user identification capability. However, it substantially requires large spreading factor as well as lower coding rate for error correction; achievable throughput performance was limited. In this paper, we introduce a channel ranking and variable spreading factor to improve the system throughput performance while maintaining BER degradation. Effectiveness of the proposed approach is clarified through computer simulation.","PeriodicalId":409591,"journal":{"name":"2019 International Conference on Advanced Technologies for Communications (ATC)","volume":"29 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":"124904141","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}
