Broadcast anti-jamming systems
Computer Networks, 2001 In a traditional anti-jamming system a transmitter who wants to send a signal to a single receiver spreads the signal power over a wide frequency spectrum with the aim of stopping a jammer from blocking the transmission. In this paper, we consider the case that there are multiple receivers and the transmitter wants to broadcast a message to all ...

Jamming Modulation: An Active Anti-Jamming Scheme [PDF]
IEEE Transactions on Wireless Communications, 2023 Providing quality communications under adversarial electronic attacks, e.g., broadband jamming attacks, is a challenging task. Unlike state-of-the-art approaches which treat jamming signals as destructive interference, this paper presents a novel active anti-jamming (AAJ) scheme for a jammed channel to enhance the communication quality between a ...

Optimal anti-jamming strategy in sensor networks
2012 IEEE International Conference on Communications (ICC), 2012 Wireless sensor networks have been widely applied to various application domains such as environmental monitoring and surveillance. Because of reliance on the open transmission media, a sensor network may suffer from radio jamming attacks, which is easy to launch but difficult to defend.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Methods based on convolutional neural networks (CNNs) have become a vital offshoot for hyperspectral image (HSI) classification. In recent years, the 3-D CNN (3-DCNN) has become dominant due to its excellent capability of extracting features.
