RIS-based indoor wireless communication signal enhancement system by Kui TANG, Qi HU, Junming ZHAO, Ke CHEN, Yijun FENG

“…By utilizing the tunable performances of the reconfigurable intelligent surface (RIS) to manipulate the reflected electromagnetic waves, an indoor wireless communication signal enhancement system was constructed, which could improve the signal quality of the receiving terminal in where the initial wireless signals were weak.First, a RIS unit cell with dynamically tunable phase characteristics was designed, and the dynamic change of the 2 bit reflection phases was realized by switching the working states of the two active diodes.Then, experiments were conducted to verify that the proposed RIS could dynamically reshape the beam direction.Finally, a host computer and field programmable gate array (FPGA) were used to realize the intelligent control of the coding sequences applied onto the proposed RIS.By changing the spatial phase distribution on the RIS aperture, the output beam could be controlled in real-time.By traversing the pre-loaded coding sequences, the enhancement of received signal in indoor wireless environments had been experimentally demonstrated.Both simulation and experiment results verify that the proposed RIS system can effectively and dynamically improve the quality of the indoor wireless signals.The received signal is increased by an average of 8.9 dB, with a maximum of 22 dB.The proposed work may provide basic hardware technical support for the optimization of 5G and the next-generation communication networks.…”

Efficient authentication scheme for cross-trust domain of IoV based on double-layer shard blockchain by Xuejiao LIU, Qiang ZHONG, Yingjie XIA

“…To solve the problems of poor scalability, slow synchronization of authentication information, and high authentication overhead in cross-trust domain message authentication in the Internet of vehicles (IoV), an efficient authentication scheme for cross-trust domain of IoV based on a double-layer shard blockchain was proposed.A double-layer shard blockchain architecture was designed for lots of cross-trust domain message authentication by constructing blockchains on different entity levels in all domains to improve the scalability of the system and ensure secure and efficient sharing of cross-domain information.A blockchain sharding method based on the Metis graph partitioning algorithm for IoV was proposed to balance loads of each shard and adapt to the uneven distribution of authentication information on different road segments in IoV, thereby improving the efficiency of synchronizing a large number of authentication information on the chain.A batch authentication scheme based on certificateless public-key cryptography (CL-PKC) was proposed, which reduced the authentication overhead of cross-domain messages by enabling batch authentication of messages from different trust domains.Experimental results show that the proposed scheme effectively improves the authentication efficiency of cross-trust domain messages.Compared with other schemes, the proposed scheme reduces the computational overhead of a large number of cross-domain message authentication by more than 26.4%.…”

Rolling bearing fault diagnosis based on parameter optimized VMD and improved GoogLeNet by LI Haoran, LIU Deping

“…A rolling bearing fault diagnosis method based on parameter-optimized variational mode decomposition (VMD) noise reduction and GoogLeNet network with improved attention mechanism was proposed.MethodsThe local minimal envelope entropy was used as the fitness function, and the sparrow search algorithm (SSA) was used to optimize the VMD parameter combination; the optimized VMD algorithm was used to decompose the bearing vibration signals to obtain several modal components, and the signals were reconstructed by filtering the modal components with rich fault features according to the envelope entropy and kurtosis; the reconstructed signals were used to construct the feature matrix and input into the improved GoogLeNet network to complete the diagnosis.ResultsThe test results show that the diagnostic accuracy of the method is 95.5% to 99.8% under different noise backgrounds, which is better than other methods in terms of noise robustness.…”
