An anti-jamming framework of spread spectrum communications with ICA
SPIE Proceedings, 2012When jamming signal is strong enough, the performance of spread spectrum (SS) communications will decline quickly. According to the independence between the SS signal and the jamming signal in baseband, a novel anti-jamming framework of SS communication with independent component analysis (ICA) is proposed in this paper.

Multi-Subchannel Spread Spectrum for Anti-jam Communications
2012 International Conference on Industrial Control and Electronics Engineering, 2012This paper presents a novel anti-jamming wireless communication system called Multi-Subchannel Spread Spectrum (MSCSS). It is based on M-ary spread spectrum (SS), direct sequence spread spectrum (DS-SS), orthogonal frequency division multiplexing (OFDM), and multi-carrier code division multiple access (MC-CDMA).

Randomized channel hopping scheme for anti-jamming communication
2010 IFIP Wireless Days, 2010Jamming attacks have been recently studied as wireless security threats disrupting reliable RF communication in a wireless network. By emitting noise-like signals arbitrarily on the shared wireless medium, a jammer can easily disturb the network. Countermeasures such as Frequency-Hopping Spread Spectrum enable nodes to avoid the jamming attacks by ...

(T, ∊)-Greedy Reinforcement Learning for Anti-Jamming Wireless Communications
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020In this article, we propose a(τ, ϵ)-greedy reinforcement learning algorithm for anti-jamming wireless communications, which chooses previous action with probability τ and applies ϵ-greedy with probability 1–τ. The key idea of our algorithm is that the more valuable the previous action is, the higher probability of directly performing it at the current ...

Randomized positioning DSSS for anti-jamming wireless communications
2016 International Conference on Computing, Networking and Communications (ICNC), 2016Traditional anti-jamming approaches like Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) require the sender and the receiver to share a secret key prior to their communication. If this key is compromised by the jammer, the jammer can then generate the frequency hopping patterns or the spreading codes used by the ...
