In this paper, based on the traditional M-array FSK modulation (MFSK/FH) system, an array antenna using the adaptive beamforming (BF) technique is adopted in the traditional MFSK/FH receiver (i.e., MFSK/FH-BF system), which improves the anti-jamming performance. Firstly, a modified FH-BF receiver using a uniform circle antenna (UCA), which is suitable for FH waveform, is proposed to reduce the effect of hopped frequency on the directions of the beam pattern. Then, the numerical relations among the FH parameters (e.g., the number of frequency slots), BF parameter (e.g., the number of snapshots), and system performance (bit-error rate and output signal-to-interference-plus-noise ratio) are systematically analyzed by theoretical analysis. Finally, the performance of the MFSK/FH-BF system is verified by simulation analysis. The theoretical and simulation results show that the direction of the beam pattern of the proposed BF-MFSK/FH system converges fast. On top of that, the proposed system is shown to be robust and capable of outperforming traditional systems with single frequency technique and single spatial technique (e.g., MFSK/FH system and MFSK-BF system) under complex jamming environments. It can be deployed in satellite systems, battlefield communication, and 5G cellular networks.","PeriodicalId":431851,"journal":{"name":"2022 7th International Conference on Communication, Image and Signal Processing (CCISP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129594243","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}

Due to the property of the background suppression and the natural topological graph structure, most of the current researches based on the skeleton graphs construct spatial-temporal graph convolutions. However, due to the forward propagation of the network, the semantic features from joints and bones in the shallow layers may be dispersed in the long diffusion process. To make better utilization of the semantic feature information, we proposed a densely connected and multiple temporal graph convolution network (SMT-DGCN), which fully utilizes the features of each layer by introducing the dense connectivity mechanism into the ST-GCN network, and uses multiple temporal convolution to extract discriminative temporal motion features. Compared to traditional GCNs, our network architecture has the following two innovative advantages: 1) By densely connecting each layer to the semantic features, we are able to reuse features and improve feature utilization compared to the base network. 2) In the temporal modeling stage, the multiple temporal convolution module is employed, which can enrich and refine the temporal features. Experiments on the NTU-RGBD dataset demonstrate that our proposed model outperforms most existing studies.","PeriodicalId":431851,"journal":{"name":"2022 7th International Conference on Communication, Image and Signal Processing (CCISP)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121143699","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}

Aviation managers should always monitor the distance, direction, and altitude of aircrafts to avoid emergencies, but the detection of low elevation angle targets by a radar is easily affected by the terrains;particularly, the multipath, target, and ground reflections can lead to superposed echo signals, which would interfere with the target detection by the radar, and reduce the detection probability and detection accuracy of the radar. Furthermore, different terrains, such as mountains, plains, and oceans, have different detection effects on the radar. Therefore, a high-resolution goniometer for three-dimensional radar systems should be designed that can be used under various terrain conditions. The present study systematically describes the effects of multipath reflections on radar detection, including the processing methods as well as the advantages and disadvantages of various algorithms, and proposes a method combining multiple goniometric algorithms. Simulation tests show that the high-resolution goniometric design can effectively improve the goniometric accuracy of the radar, which fully demonstrates the feasibility of the high-resolution goniometry design in a three- dimensional radar system.","PeriodicalId":431851,"journal":{"name":"2022 7th International Conference on Communication, Image and Signal Processing (CCISP)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122644426","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}
