Robust resource allocation algorithm for multicarrier NOMA security communication system by Yu ZHANG, Xiongwen ZHAO, Xiaoqing WANG, Suiyan GENG, Peng QIN, Zhenyu ZHOU

“…To improve the spectrum efficiency and enhance the information security of wireless network, a sum secrecy rate maximization-based robust resource allocation algorithm was proposed for a downlink multicarrier NOMA security communication system.Firstly, the artificial noise (AN) precoding vector was designed to be orthogonal to the legitimate channel, so that the legitimate transmission would not be affected by the AN.Then, considering the constraints of rate requirement of each user and the maximum transmit power of base station, a joint AN precoding, downlink data precoding and subcarrier allocation optimization problem was formulated under eavesdropping channel uncertainties.To solve that non-convex problem, it was decomposed into two joint optimization subproblems: precoding optimization and subcarrier allocation.The former was solved based on S-procedure and block coordinate descent (BCD) algorithm, the latter was solved by dynamic matching theory.Simulation results demonstrate that the proposed algorithm has good robustness and can effectively improve the sum secrecy rate.…”

Analysis and Design of an Optimal Noise Estimation and Cancellation Filter in Wireline Communication by Mohammad Emami Meybodi, Hossein Shakiba, Ali Sheikholeslami

“…This paper presents a comprehensive study of noise prediction and cancellation techniques in high-speed wireline communication systems. Feedforward and feedback architectures are compared, and it is found that while feedforward architecture can reduce total noise power, it fails to reduce symbol error rate (SER) due to unreliable noise estimation. …”

Integrated sensing and communications for Internet of vehicles：current status and development trend by Xiang CHENG, Haotian ZHANG, Zonghui YANG, Ziwei HUANG, Sijiang LI, Anlan YU

“…The Internet of vehicles, the most important component of intelligent transportation system (ITS) in the future, is one of the most important technologies to achieve smart traffic and convenient travel for the people.With the vigorous development and continuous utilization of sensing and communication functions, the combination of these two functions, that is, integrated sensing and communications (ISAC) technology of vehicular communication networks, has become the current research hotspot and is of great significance to the development of ITS.Firstly, two different models of ISAC system, i.e., functional ISAC and signaling ISAC were defined and differentiated.Then, for the two different ISAC models, the existing works were reviewed and analyzed comprehensively.Finally, the future development directions and technical challenges of ISAC design in vehicular communication networks were proposed.…”

Multi-feature fusion classification method for communication specific emitter identification by Zunwen HE, Shuai HOU, Wancheng ZHANG, Yan ZHANG

“…A multi-feature fusion classification method based on multi-channel transform projection, integrated deep learning and generative adversarial network (GAN) was proposed for communication specific emitter identification.First, three-dimensional feature images were obtained by performing various transformations, the time and frequency domain projection of the signal was constructed to construct the feature datasets.GAN was used to expand the datasets.Then, a two-stage recognition and classification method based on multi-feature fusion was designed.Deep neural networks were used to learn the three feature datasets, and the initial classification results were obtained.Finally, through fusion and re-learning of the initial classification result, the final classification result was obtained.Based on the measurement and analysis of the actual signals, the experimental results show that the method has higher accuracy than the single feature extraction method.The multipath fading channel has been used to simulate the outdoor propagation environment, and the method has certain generalization performance to adapt to the complex wireless channel environments.…”
