Programmable data processing method and system design for polymorphic network
Published 2022-04-01“…Aiming at the problems of compatible with multiple route identification, network protocols and network application data processing faced by multimodal networks, a programmable data processing method compatible with multiple modes was proposed.Through the mode recognition and classify module to identify packets of different network modes, the data type, offset and length were used to represent multiple types of data, and the modal data processing pipeline was formed by using the matching action data table with selectable matching algorithm and processing action to process data of different types of network.A prototype system for data processing of polymorphic network was implemented and verified by using the proposed method.Experimental results show that the modal data processing pipeline can isolate the network of different modes and ensure the performance independence, the type of matching algorithm and the length of the processed data will affect the forwarding performance of the system, while the type of data will not.…”

旋转叶片异步振动参数辨识方法及试验验证
Published 2021-01-01“…Based on the principle of blade tip timing( BTT) and the vibration principle of one degree of freedom,the parameter identification algorithm of rotating blade asynchronous vibration is established by using all phase FFT( apFFT) and least square method.The algorithm is verified by numerical simulation,and the test parameter and empirical value of the rationality for sensor layout are given.The tests of asynchronous vibration parameter identification were launched on a fan rotor,while high pressure nitrogen was used to shock the blades to produce single frequency absolute occupancy vibration.Results show that the method for asynchronous vibration identification could accurately identify blade vibration parameters,and the vibration frequencies of all blades obtained are exactly the same.Frequency identification accuracy is high with the maximum relative error of 1.12% using strain analysis frequency as a baseline.Results verify that the method of asynchronous vibration parameter identification is correct.…”

A blockchain sharding scheme in edge computing
Published 2023-12-01“…The low security and poor privacy of the data in edge computing restrict the development of edge computing.Block chains can provide security for data in edge computing using their own tamper resistance, while protecting privacy by use of traceability.But the bottleneck of blockchain's scalability has become a barrier to their application in the field of edge computing.To solve the problem that blockchain can not meet the needs of a large number of nodes to process data at the same time when applied to edge computing, a two-layer sharding scheme was presented, which meets the needs of edge computing scenarios.Geographic location-based partitioning of nodes was implemented using the improved K-means algorithm, and a local blockchain network consensus (LBNC) algorithm was designed based on the idea of delegated proof of stake (DPoS) and practical Byzantine fault tolerance (PBFT).Simulation results show that the proposed scheme has less delay and higher throughput than those of PBFT, and the total throughput increases with the number of shards.…”

Design of precoding matrices in MIMO full duplex two-way security communication system
Published 2020-10-01“…The design of precoding matrices was studied in the multiple input multiple output (MIMO) full-duplex two-way security communication system where legitimate nodes transmit the confidential information accompanied by the artificial noise while receiving information.For the scenario where the perfect channel state information (CSI) of legitimate channels and eavesdropping channels was available,the difference of concave/convex (DC) programming was used to optimize the precoding matrices of the information signal and the artificial noise for the maximization of the secrecy sum rate.For the scenario where the CSI was imperfect,the channels were modeled by using worst-case criterion and the weighted minimum mean square error algorithm was used to get the robust precoding matrices of the information signal and the artificial noise.The simulation results prove that the proposed algorithm can effectively promote the secrecy sum rate of the system.…”

Research on accurate ranging of UWB under indoor environments
Published 2007-01-01“…The accurate ranging ability of ultra wideband(UWB) signal under IEEE 802.15.4a indoor channel model was studied.An improved time-of-arrival(TOA) estimation algorithm which utilizes region search and threshold comparison was proposed.By statistical analysis on certain characteristics of the CM1 and CM2 channel profiles,the probability model of TOA estimation error was deduced.The thresholds of the proposed TOA estimation algorithm were then set by limiting the error probability to the lowest level.The mean absolute ranging errors under different SNR were simulated.Results show that high enough SNR should be guaranteed in order to obtain centimeter-level ranging precision under in-door environments,while extremely high SNR would not help to improve the ranging precision any more but lead to a performance floor.The results have instructional significance on designing localization algorithms and transmission power control in practical ranging.…”
