Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

IEEE Transactions on Vehicular Technology, 2021 This correspondence reveals the potential of reconfigurable intelligent surface (RIS) in anti-jamming communications. In particular, we consider an aerial RIS (ARIS) that can be flexibly deployed in the air so as to mitigate jamming attacks and enhance ...

Jamming and irreversibility [PDF]
Granular Matter, 2019 We investigate irreversibility in soft frictionless disk packings on approach to the unjamming transition. Using simulations of shear reversal tests, we study the relationship between plastic work and irreversible rearrangements of the contact network.

Jamming and Anti-Jamming Strategies of Mobile Vehicles [PDF]
Electronics, 2021 Anti-jamming games have become a popular research topic. However, there are not many publications devoted to such games in the case of vehicular ad hoc networks (VANETs). We considered a VANET anti-jamming game on the road using a realistic driving model.

Research on the Compound Jamming Method against FDA-MIMO Beamforming
Applied Sciences, 2022 Frequency diverse array multiple-input multiple-output (FDA-MIMO) radar solves the problem of angle pointing and range pointing during beam transmission due to its unique range-angle dimension dependent, which gives it good characteristics against main ...

Jamming of LoRa PHY and Countermeasure
IEEE Conference on Computer Communications, 2021 LoRaWAN forms a one-hop star topology where LoRa nodes send data via one-hop up-link transmission to a LoRa gateway. If the LoRa gateway can be jammed by attackers, the LoRa gateway may not be able to receive any data from any nodes in the network.
