Anti-jamming of chaotic signals [PDF]
Proceedings of Third International Conference on Signal Processing (ICSP'96), 2002 It is found that the amplitude-modulation disturbance can make the chaotic output signals of Chua's (1986) circuit jump into a limit cycle. This is because the limit cycles usually encircle the chaotic orbits in the phase portraits of the Chua's circuits. The four jamproof methods adopted in our physical experiments are the limiter for clipping the sum

Broadcast anti-jamming systems
IEEE International Conference on Networks. ICON '99 Proceedings (Cat. No.PR00243), 2005In a traditional anti-jamming system a transmitter who wants to send a signal to a single sender 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 sender wants to broadcast a message to all receivers such ...

Discussion of GPS Anti-Jam Technology [PDF]
GPS Solutions, 1999 The Global Positioning System (GPS) satellita navigation aiding system, sometimes called NAVSTAR, has become a utility to the military and many civilian areas. GPS, currently consisting of 24 satellites, is used by the military for navigation, precision weapons delivery, and the future digital battlefield.

Anti-Jamming Filtering in the Autocorrelation Domain
IEEE Signal Processing Letters, 2004An anti-jamming filtering technique is presented that it fully eliminates the jamming (or noncooperative) signal and its performance is noise-independent. This technique uses multiple receivers; a filtering process explores the nonoverlapping properties of the signals in the autocorrelation domain; and a matching of the input and the output statistics.

An Improved Radar Anti-jamming Method
2018 IEEE 3rd International Conference on Signal and Image Processing (ICSIP), 2018When the interference enters from the main lobe direction of the radar, the adaptive side-lobe cancellation algorithm will lead to beam distortion, main lobe pointing offset, and affect the detection of the target. This paper proposes a phase-coded signal system.

A study of GPS jamming and anti-jamming
2009 2nd International Conference on Power Electronics and Intelligent Transportation System (PEITS), 2009The weaknesses of GPS (Global Positioning System) is vulnerable to be jammed, so the study of jamming and anti-jamming of GPS has drawn more and more attention. In this paper, it analyzes the performance of GPS jamming and the anti-jamming of GPS receiver about blanket jamming.
