Multi-feature fusion classification method for communication specific emitter identification
Published 2021-02-01“…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.…”

Research on Dynamic Equalization of Optical Power for Satellite-Ground Laser Communication
Published 2021-06-01“…Aiming at the problem of light intensity scintillation caused by atmospheric turbulence at the receiver of satellite-ground laser communication will aff ect the communication quality, an optical power balance system based on gain competition was studied.The experiment verifi ed that the received power fl uctuation increased the communication bit error rate.The static output curve of the equalization system under gain competition was studied and the equalization performance of the dynamic time domain signal was tested.The experimental results showed that the system could compress the power fl uctuation range of the dynamic signal to 4 dB.…”

Joint power control for untrusted relay cooperation-based confidential communication
Published 2014-11-01“…The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure communication between BS and multiple MS,destination-based jamming (DBJ) scheme was adopted.With the assumption that all MS had fixed transmit power,the joint UR and BS power control which aims at maximizing system sum secrecy rate was discussed.For this problem,analysis indicated that it was equivalent to joint access control and power allocation problem thus its NP-hard.Through problem relaxation,a suboptimal MS access control and alternatively power allocation algorithm was provided.This algorithm is proved to have polynomial complexity and can converge to at least a suboptimal solution for original problem.Simulation results show that compared with the benchmark algorithms,the proposed suboptimal algorithm is better in the achievable secrecy rate performance.…”
