With a channel state information (CSI) between source and eavesdropper, a Alice null the received signal for eavesdropper with zero forcing beamforming (ZFB). But the CSI between source and eavesdropper is hard to achieve in secure communication. In this work, we propose the torch node in secure communication. The torch is assist node for secure communication that only report the CSI between source and the torch node. And we consider that the CSI of the torch node and some of eavesdroppers that close to torch node has a correlation. With this assumption, the Alice improve the secure outage with the CSI from the torch node. The study show that when transmit antennas of source is many then torch node bring the transmit power gain.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125251877","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}

TBO-ZFB dynamically switches between a beamforming weight vector and a zero-forcing beamforming (ZFB) weight vector (using linear precoding for first mobile station (MS)) by comparing the values between a second MS's signal-to-noise ratio (SNR) and a predetermined threshold. We provide that the threshold is satisfied with the second MS's outage constraint.

A different but related problem is InterCell Interference Coordination, where two network nodes with overlapping coverage regions simultaneously transmit to UEs attached to them, but coordinate so as to not cause cross-cell interference. In this paper, we propose a novel method called `Active NullForming' which mitigates cross-cell interference using interference presubtraction. We show that we can achieve significant performance improvement over existing methods such as zero-forcing beamforming.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122825924","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}

Based on these advantages, the DSPG is suggested in this paper as a viable candidate suitable to a fine-grain leakage control scheme, where logic blocks go in and out very frequently and shortly between the active and sleep modes.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123411027","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 main idea is to integrate the sensing capability into UHF RFID tags thanks to the relation between physical read-range and permittivity of object in that we labeled RFID tags. From the knowledge in variation of food permittivity in function to time by experimental characterization, it is possible to detect the contamination time from which the food becomes improper for consumption based on the measurement of read-range with designed sensing tags. This low-cost UHF RFID passive sensor was designed and experimentally tested on beef with the same storage conditions in supermarket.

The stage is based on a compliant mechanism with flexure hinges and the two piezoelectric elements which are used as motion excitation sources. The SIDM (Smooth Impact Driving Mechanism) is applied for rotation motion. To evaluate the designed stage, the finite element analysis was applied by means of commercial software ANSYS.

Unlike some existing methods based on spatial domain watermarking techniques, the even-odd quantization algorithm is applied in our paper to embed all bit plane images decomposed from a single watermark image into only selected robust Discrete Cosine Transform (DCT) coefficients of 8×8 blocks from a host video. As a result, our method not only has high capacity of embedded information but also obtains high quality of watermarked video. Moreover, in order to obtain the security, a secret key is used to scramble embedded blocks and the watermark image is extracted without the host video. The experimental results demonstrate that our proposed method is robust against attacks of compression and addition of noise.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127705606","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}
