The unit it utilizes has excellent amplitude and phase characteristics, greatly facilitating the construction of the proposed metasurface and laying a solid foundation for the improvement of efficiency. According to non-diffraction theory and anomalous reflection law, two metasurfaces are designed for comparison. The simulation results show that the designed metasurfaces successfully realize the non-diffractive beam with a focusing distance of 126 mm (2.44 λ0), and can bend the normally reflected wave to the direction 10° from the +z direction in a vertical plane 45° away from the +x direction. The average efficiency of the metasurface within the focusing range is as high as 84.5%, thus could be used as radio energy transmission, telecommunication multiplexing and accurate detection devices.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"7 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116870087","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}

Recently, the ReID (Person re-identification) algorithm has shown that the local features of pedestrians are used to describe various parts of the body, the global features of pedestrians are used to represent the overall information, and the local features of relationships are used to make certain connections between local features to form more discriminative features. Although these algorithms have a certain effect on pedestrian re-identification, their recognition accuracy is still not satisfactory. To solve these problems, we propose a novel multi-feature extraction fusion model (MFEFM). It can extract three different features of pedestrian images at the same time and merge them together to form a more discriminative feature. First, use ResNet-50 as the infrastructure to extract basic features. Then, global maximum pooling (GMP) is used to extract local features of pedestrian images, global average pooling (GAP) is used to extract global features, and pose-estimator is used to extract key point features in parallel. Finally, we use the relationship network to form connected local features and key point features, and then connect these three features together.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115545087","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}

McEliece cryptosystem has been shown to quantum resistant, which is faster and simpler compared with RSA. When different types of codes are used, most of the ciphers are easy to be cracked. Initially, the keys were all large matrices. For example, the size of the generating matrix of Goppa codes is 1024×524, and it increases exponentially with the increase of the coding length and the number of generated polynomials. In this paper, we use QC-MDPC codes instead of Goppa codes to reduce the key sizes and improve the decoding algorithm, which can resist all kinds of attacks. In the 5G era of the Internet of things, the application of this cryptosystem can guarantee more access security.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115239915","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, the cross-modulation among different subchannel would greatly degrade the performance of system due to the non-linearity of the large-scale amplifier array. Hybrid precoding technology is a general candidate for this problem due to its capability for linearization, and the predistortion matrix would be the key factor for its performance. In this paper, a memory polynomial model is adopted for modelling nonlinear power amplifier (PA) and Recursive Least Square based digital predistortion (RLS-DPD) algorithm is proposed for parameter training for hybrid predistortion module. The proposed RLS algorithm extracts the parameters of the digital predistortion module through adaptive learning in the training phase. Adaptive learning refers to the process of using the filter parameters obtained at the previous moment to automatically adjust the parameters at the current moment according to the estimated error, which minimizes the cost function. The simulation results show that the RLS-DPD algorithm can reduce the system bit error rate by 27.778%, error vector magnitude (EVM) by 67.961 % at 8dB SNR, and enable the nonlinear OFDM signal to be demodulated correctly at the terminal.","PeriodicalId":124337,"journal":{"name":"2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116148810","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}
