Low frequency acoustic source imaging method based on coprime position non-synchronous measurement by Juan WEI, Yutao HE, Fangli NING

“…In order to solve the problem that the acoustic imaging resolution was low under the condition of low frequency and low SNR due to the limited microphone array aperture and element density, a high resolution imaging method of low frequency and low SNR sound source was proposed based on the non-synchronous measurement of the coprime position.Firstly, the acoustic signal was received at the coprime position and the missing cross-spectrum matrix was calculated by the mobile prototype array.Then, the improved accelerated proximity gradient algorithm was used to complete the missing cross-spectrum matrix, and the complete cross-spectrum matrix was vectorized.Finally, the virtual array signal model was established and solved.The simulation results demonstrate that the proposed method has lower positioning error, higher imaging resolution, and better robustness and noise immunity than the previous methods under the condition of low frequency and low SNR.…”

Reinforcement learning based group key agreement scheme with reduced latency for VANET by Tangwei1 XU, Hailu ZHANG, Chuhuan LIU, Liang XIAO, Zhenmin ZHU

“…Key agreement scheme of vehicle ad hoc networks (VANET) determines the privacy and security against user identity-based attacks,such as spoofing attack.The existing work updates the group shared key at a fixed frequency,which increases the processing latency of the key updates and the encryption and decryption of group communication.A reinforcement learning based dynamic key agreement scheme was proposed to enable the group cluster head to optimize the key update frequency and key length.This scheme optimizes the calculation latency of encryption and decryption based on the number of surrounding vehicles,the previous key update records without the knowledge of the traffic flow model and the access-driven cache attack model.Simulation results show that this scheme reduces the transmission delay of the communication overhead and the computational latency of encryption and decryption,and improves the security of the group key compared with the benchmark scheme.…”

Simulation of film bulk acoustic resonator based on two-dimensional phononic crystals by Linhao SHI, Weipeng XUAN, Lingling SUN, Shurong DONG, Hao JIN, Jikui LUO

“…A new structure of film bulk acoustic resonator (FBAR) based on phononic crystal (PnC) was proposed.The phononic crystal was used as the acoustic reflection layer at the bottom of the bulk acoustic wave resonator, which has the characteristics of high reflectivity and low transmittance of elastic wave in its band gap.The band gap characteristics of four kinds of phononic crystals with different structures were calculated by the finite element software COMSOL Multiphysics.The main conclusions are as follows.If the bulk acoustic resonator is working within the band gap of the phononic crystal, PnC can be used as the bottom acoustic reflection layer of the FBAR.With using PnC as the acoustic energy reflect structure, the impedance curve of FBAR is smooth, and the quality factor is closed to traditional FBAR with a value of 859 and effective mechanical coupling coefficient of 6.32%.…”
