In this paper, the outage performance for a full-duplex (FD) relaying satellite-terrestrial system is investigated. The system consists of a satellite source, a relay, and two users. Firstly, the satellite transmits the information of two users to the FD relay, and then the relay decodes and forwards the information to both users. Herein, the non-orthogonal multiple access protocol is used to incorporate the signal of two users. We investigate the system outage performance in the presence of residual self-interference of the relay and derive the exact expressions of outage probability for two users. Moreover, the accuracy of the results is verified with Monte-Carlo simulations.

The main type of communication system can be divided into base-band transmission and pass-band transmission. For baseband transmission, polar NRZ coding is utilized among common PCM coding schemes to achieve the best error performance when the SNR stays the same. Matched filter receiver is adopted to carry on error analysis. For pass-band transmission, signal-space is introduced to simplify the procedure with a few examples. Then a new Euclidean space is mentioned, which is sort of different from the former, to directly map sending bits with their actual position on the space. 2D and 3D space, related to the 4-ary system and 8-ary system respectively, is depicted to illustrate the point. At last, a potential application for pixel maps is considered to qualitatively underscore the error impact on the practical system.

The quality of facility layout is related to the operational efficiency of the entire system. Based on bibliometric methods, 859 related papers on the theme of facility layout included in the Web of Science core dataset from 2002 to 2021 were analyzed. First, through the visualization tools of Web of Science, the issue of facility layout is analyzed from the annual publication volume, journals and research directions. Next, based on the Citespace software, the cooperation and citation relationships among countries, institutions, and authors are analyzed from the macro, meso, and micro levels, and the cooccurrence analysis of keywords and nominal terms is carried out to generate a visual knowledge map, and to solve the problem of facility layout. The research status, hotspots and trends are reviewed. The results show that the problem of facility layout has been a hot research area. However, there are many and scattered situations in China's facility layout research, and it is necessary to strengthen cooperation. In addition, there are few studies in the fields of digital facility layout, smart factory, and digital twin, which need to be focused on.

At present, the convolutional neural network is deepening in level and has a huge amount of computation, so it is difficult to realize application in scenarios with low computing capacity. Therefore, this paper proposes a method based on channel pruning and weight quantization to reduce the amount of computation and compress the image super-resolution to reconstruct the network model IDN. Experimental results show that the proposed method effectively compresses the model structure, greatly shortens the calculation time of the model and makes the model more lightweight under the premise that the performance indexes are basically unchanged.

Target detection technology is a typical application in the military field. It can quickly and accurately find and identify all kinds of enemy vehicle targets in the battlefield, and respond to all kinds of battlefield targets more quickly, which has become the key to improve the battlefield situation. Because the battlefield environment is very complex, the traditional target detection algorithm is not ideal when detecting targets in complex scenes. Therefore, a target detection algorithm for armored vehicles of military tanks based on improved YOLOv3-tiny is proposed, which realizes the automatic detection of military targets in complex environments by deep learning. Firstly, based on YOLOv3-tiny algorithm, ResNext residual network is added to replace the original feature extraction network, which better improves the problem of missing and false detection of small targets and optimizes the convolution network structure. Then, the dense network is introduced, and the features of different layers are fused to realize feature reuse, which improves the efficiency of extracting better features of target vehicles, strengthens the network's ability to learn features, and improves the detection effect. Experimental results show that the recall rate and precision rate are increased by 4.62% and 3.79% respectively, the average precision rate is increased by 4.32%, and the frame rate can reach 78 frames/s.

Cellular-based Internet of Things (IoT) network has huge potential, i.e., enhancing security, promoting smart cities, and so on, while the interference will become very serious with the increasing densification of cells. Reconfigurable intelligent surface (RIS) has tremendous potential to alleviate interference. In this paper, we use RIS to improve the system performance via reducing the interference from neighboring cells and users in the same cell. We establish an optimization problem to maximize data rate with the constraint of the power of base stations (BSs). Due to the nonconvexity of the optimization problem, it’s difficult to obtain the optimal passive beamforming and active beamforming directly. Thus, we propose the fractional programming (FP) method to approximate non-convex objective function to tractable forms. Then, we utilize an improved block coordinate descent (BCD) algorithm to find suitable passive and active beamforming for the presented two convex functions. Simulation results demonstrate that the BCD method has better system performance than the non-RIS and random phase schemes.

A communication system for remote communication is designed. The system uses FPGA as the main control unit and pulse position modulation PPM as the basic modulation mode. Aiming at the problem that frame synchronization can not be realized in PPM communication, this design adopts the way of adding frame head frame tail structure and inserting protection gap to ensure information synchronization. In addition, the four-phase clock synchronization extraction method is used in the synchronous demodulation of PPM signal at the receiving end, which effectively reduces the error rate of FPGA in the working process, and greatly simplifies the design of the whole system. In this design, the encoding of PPM will use Gray code mapping to reduce the bit error rate. Finally, the system achieves a faster communication rate, and the BER of the actual test is low.
