Parameter estimation of frequency hopping signal based on time-frequency matrix LCM by Jiamin LIU, Zhijin ZHAO, Junna SHANG, Xueyi YE

“…To improve the performance of the parameter estimation of frequency hopping signal under low signal-to-noise ratio, a parameter estimation algorithm of frequency hopping signal based on time-frequency matrix LCM was proposed.Considering the different characteristics of time-frequency distribution of frequency hopping signal and noise, the mean local energy comparison value of the time-frequency matrix under different scale sliding windows was used, and the multi-scale local energy comparison feature matrix was introduced, so the time-frequency matrix P that only contains the time-frequency information of the frequency hopping signal could be obtained through this feature matrix and the adaptive threshold separation.And then, by extracting the time-frequency hopping information from P, the period, hopping time and frequency of the frequency hopping signal could be accurately estimated.The simulation results show that compared with the traditional local contrast measure (LCM) and morphological filtering method, the proposed algorithm has better frequency hopping signal extraction effect and higher parameter estimation accuracy.And then the tests of the algorithm on the DSP+FPGA hardware system verify the effectiveness and practicability.…”

Beam Hopping Beam Optimization and Resource Allocation Algorithm Based on Phased Array by Mengting HAO, Chen ZHANG, Gengxin ZHANG

“…Beam hopping technology can provide enough fl exibility and high resource utilization for satellite communication system, and shows good performance in broadband satellite communication system.However, the existing beam planning scheme of beam hopping technology is relatively fi xed and can not change with the change of service demand characteristics.For the situation of uneven distribution of user demand and scattered location, the advantages of beam hopping technology are diffi cult to play.To solve the above problems, a beam optimization method was proposed, which used the agility characteristics of phased array antenna to adjusted the size of beam according to the characteristics of service distribution, so as to made the service demand in each beam more balanced.On this basis, from the perspective of matching the demand with the actual transmission capacity, the minimization n-order diff erence objective function was established, the time slot resources allocated in each beam were solved by convex optimization algorithm, and the overall satisfaction and system delay of the system before and after beam optimization were compared.The simulation results showed that compared with the traditional beam planning scheme, the algorithm could improved the overall satisfaction of the system, reduced the system delay and improved the access success rate of the users.…”

Two-hop cover-based access control scheme for wireless sensor networks by DU Zhi-qiang1, SHEN Yu-long1, MA Jian-feng1, ZHOU Li-hua1

“…In order to support randomly moving users,a THC（two-hop cover） algorithm and a two-hop cover-based ac-cess control scheme were proposed.The proposed algorithm made two-hop nodes be able to retrieve access control in-formation of user’s in time through diffusing the information periodically.The scheme based on THC algorithm,the se-curity mechanisms of Merkle hash tree and one way chain,as well as distributed access control mode,its main contribu-tion was it supports randomly moving users for the first time.The analyses and experiments have shown that the pro-posed scheme can be applied to both mobile and stationary user and have several advantages over the current access con-trol methods of low cost in computation,communication and storage,and resistance to node capture,query replay and DoS attacks.…”
