The system consists of a cylindrical electromagnetic field, a spatial device, a plane measuring ring, and a measuring circuit set. The cylindrical electromagnetic field spatial device is a hollow cylindrical structure. A plane measuring ring is arranged on the inner wall of the cylinder along the vertical cylinder wall, and the measuring ring can move up and down along the inner wall. A measuring rod with a ruler is arranged in the direction of the diameter of the measuring ring, and the measuring rod can rotate around the center of the measuring ring. A measuring circuit group is provided at intervals between the measuring rods. Used to obtain three one-dimensional magnetic field data in each direction of each measurement point covered by the measuring ring and then three dimensional magnetic field data are obtained. The measured data are analyzed, processed, and synthesized to form a magnetic field in which the measuring ring is located. The horizontal position of the measuring ring is adjusted, and the magnetic field of different planes is obtained. Finally, the distribution of the magnetic field is obtained. This method lays a solid foundation for further study of the spatial constant magnetic field and the fast pulsating magnetic field distribution.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121820285","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}

Firstly, we design a relay-triggered individual spectrum sensing scheme. Specifically, we exploit a relay signal generated by a cognitive transmitter (CT) who has relaying capability and acts as a full-duplex amplitude-and-forward relay to trigger the primary link's close-loop power control (CLPC) which has been frequently used in practical wireless communication application, resulting in primary transmitter adjusts its transmit power under CLPC, the CR receiver observes the energy of the primary signal and decides whether the primary receivers (PRs) are within or out of CT's coverage. Then, considering the fact that local spectrum sensing may be not reliable due to the fading and shadowing effects, we further develop the proposed individual spectrum sensing scheme to a new collaborative one where multiple CRs are involved in sensing and the common receiver combines the decisions received from cooperative CRs to get a final decision which will improve the sensing performance. Finally, the performances of the proposed schemes are illustrated by simulations.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127148454","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}

Yanan, Du Yuren","doi":"10.1109/ICEMI.2017.8265827","DOIUrl":"https://doi.org/10.1109/ICEMI.2017.8265827","url":null,"abstract":"Aiming at the problem that the traditional TLD algorithm is not accurate when the target encounters occlusion, a TLD algorithm based on Mean Shift is proposed. When the confidence level of the TLD tracking box is high, the center position of target of the TLD output is used as the starting point of the Mean Shift tracking algorithm. When the confidence level is low, the center position of the target box in the previous frame is used as the iterative starting point for the Mean Shift. The results show that the improved algorithm achieves higher precision, especially for occlusion and target jitter. In order to solve the problem that there are more useless points in the feature points obtained by uniform sampling of TLD algorithm, a more robust Susan corner point is introduced into the TLD tracking module. This algorithm can track the object through the pyramid LK optical flow after selecting the corner. It not only preserves feature points with rich information during the tracking process, but also suppresses the tracking drift caused by more useless points. The results show that this method has high robustness and real — time compared with the original TLD algorithm.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416543","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}
