A novel algorithm based on signal's steady state feature fusion method is proposed in this work to deal with the individual recognition for satellite communication, which tries to combine the extracted wavelet coefficients, bispectrum features and fractal dimension of sampled data with canonical correlation analysis (CCA). The popular kernel principal components analysis (KPCA) method is thereafter introduced to reduce the feature dimension and several familiar classifiers are designed to verify the results. It has proved that the fused features for specific individual satellite communication terminals holds evident separability that are available for traditional classification algorithm. The experiments have demonstrated the excellent performance of proposed method.

In order to ensure the reliable communication transaction of ETC, it is necessary to use radio monitoring equipment to regularly monitor the communication status of the RSU antenna in the main communication direction of ETC and the electromagnetic wave working environment around the transaction area. However, traditional large-scale radio monitoring equipment using discrete components and analog RF front-end is not suitable for mobile use in outdoor fields due to its large size and high power consumption. This paper proposes a method for detecting and locating ETC interference sources using the principle of sideband monitoring and the signal source location characteristics of phased array antennas and array scanning antennas multi-beam scanning, which greatly reduces the weight and cost of the equipment.

Considering the increasing demand for data collection in ocean, forestry, meteorology and water conservancy, we proposed a kind of satellite Internet of Things system level solution based on TT-1 satellite mobile communication system which is working well. This paper studies the satellite IoT system architecture and the transformation of the TT-1 air interface, including the physical layer design, access design of terminal and improvement of communication protocol, etc. Therefore, a brand-new kind of system which can run both the normal operation of TT-1 system and the efficient data collection business is built.

This paper proposes a 77GHz millimeter wave radar-based rear occupant detection system in a vehicle. The major focus is detecting forgotten children in a vehicle's rear seats. The radar TX chirp signal configuration is selected to detect slight movements of people (like breathing). The radar RX IF signal is processed through 2D-FFT to build a two-dimension heat map. Then, the Constant False Alarm Detection (CFAR) algorithm is used for object detecting and a 2D cloud points image is obtained which can visualize the presence of people in the vehicle. Moreover, in the simulated vehicle environment experiment, our system can correctly identify if the vehicle is occupied or not in real time.

Anti-jamming/interference is the most important issue in the wireless communication. 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.

A two-port dual-band millimeter-wave MIMO antenna based on SIW functioning in 5G is presented in this paper. Grounded coplanar waveguide GCPW is used for better impedance matching on antenna elements. This antenna is innovative in that it combines MIMO technology with SIW technology to improve isolation and communication quality. Moreover, double dumbbell-shaped slots are etched inside SIW resonator. Multi-modes are excited by this groove, which results in dual-frequency and broadband antenna performance. The antenna is printed on substrate Rogers 5880 with dimensions of 21.2X 19.2X 0.508 mm3. The proposed SIW antenna is capable of working with the 28GHz (25.74 GHz - 29.79 GHz) and 38GHz (37.18GHz - 41.8GHz) bands of 5G mmWaves. In addition, it demonstrates high isolation of more than -20 dB, good gain above 8dBi, FBR around 15dB and ECC less than 0.018 in the whole working band. It has good prospects in 5G applications.

More and more researchers are devoting themselves to skeleton-based action recognition owing to its high research value. 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.

An automatic CT image-based path planning method for lung puncture surgery is proposed due to high failure rate, time consumption, and the high radiation dose of the existing percutaneous lung puncture surgery. The method described in this paper implements automatic organ segmentation of chest CT images. It defines six constraining conditions combined with clinical a priori knowledge to find the optimal puncture path using a multi-objective Pareto optimization method. The rationality and validity of the method were validated based on 25 sets of clinical lung mass data. Experimental results show that the optimal paths found by this system all meet the clinician's surgical requirements.

Aviation is becoming progressively important with the development in science and technology, but aviation safety cannot be guaranteed without radar detection. 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.
