Directional links with pencil beams at gNodeB (gNB) and user equipment (UE) alleviates path loss by high antenna array (AA) gain at the transmitter and receiver. However, despite benefits, double directional links pose new challenges, which were absent for omnidirectional case, in particular, beam alignment in line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. Thus, the aim of current research is to analyze existing models for mmWave communication with multipath components (MPC) due to reflections from scattering points (SP) and to formalize channel model, accounting these effects in LAB scenarios for double directional link with pencil beams at the gNB and UE. Contribution of current research includes directional channel model for location-aware beamforming in 5G UDN, including account of AA size and SP displacement on the plane. Practical implications directional channel model is developed simulation tool for coarse evaluation of transmitter-angle of departure (AOD) and receiver angle of arrival (AOA) for beam alignment procedures in LAB link, depending on the dimension of antenna array and gNB, SP and UE displacement in UDN scenario.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126415009","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 effect of digital processing of an interference signal on the achievable axial spatial resolution was shown.

To address this problem, this paper designs a spectral network combining Fast Fourier Convolution (FFC) and detection network. By extending the receptive region of the network, features around the object are introduced as additional information to help detect small objects. Specifically, the FFC in the proposed spectral network extracts global features through its unique Fourier Unit: the spatial feature is first transformed into the frequency domain by the Fast Fourier transform (FFT), then a convolution block is performed to extract the frequency features, obviously this frequency-aware convolution block has a global receptive field in the spatial domain covering the whole image, and finally the features are recovered to the spatial domain using the inverse FFT. To demonstrate the effectiveness of our approach, we conduct experiments on the large remote sensing dataset DIOR, which shows that our approach has excellent performance compared to other detectors. It achieves an average accuracy (mAP) of 73.5% without any tricks.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115334434","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}

Unlike other modes, the TE111 mode has the highest Q-factor, which makes it the most useful for measurements. By registering the change in the Q-factor of this mode, the parameters of the barrier discharge plasma jet were defined by using perturbation theory. To reduce the influence of the effect of polarization degeneracy of the eigenmodes of the cylindrical resonator, a thin wire was installed inside it in a certain position.

To study the effect of existing HD digital display terminals on visual fatigue, we tested the display performance indices and recruited subjects for visual fatigue evaluation of 84 kinds of HD digital display terminals produced by 14 manufacturers on the market. The objective test results show that the blue light of the liquid crystal display television (LCD TV) is high, and the flicker of the light-emitting diode (LED) display is high too, which may lead to visual fatigue. The luminance of the tablet computer is low, which may also lead to visual fatigue. The contrast ratio of the LED display is high, which may lead to direct glare, and the specular reflectance of the tablet computer is high, which may lead to indirect glare, causing visual fatigue.
