Anti-Jamming Techniques for GPS Receivers
2001Abstract : The fundamental objective of this research project is to improve the GPS receiver performance when subjected to strong nonstationary interference. The techniques applied and proposed to achieve this objective rely on the estimation of both time-frequency and spatial signatures of the jammers.

Anti-jamming techniques for synthetic aperture radar
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009Excellent performance of SAR has aroused deep study of jamming techniques. This paper first discusses present jamming techniques and their shortcomings, then gives methodology of classifying ECCM of SAR, and at the same time, gives principle and results of signal design method, which combines orthogonal codes and random initial phase at each pulse, the

Efficient uncoordinated FHSS anti-jamming communication
Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing, 2009We address the problem of jamming-resistant communication in scenarios in which the communicating parties do not share secret keys. This includes scenarios where the communicating parties are not known in advance or where not all parties can be trusted (e.g., jamming-resistant key establishment or anti-jamming broadcast to a large set of unknown ...

A self-recovery scheme in anti-jamming communications
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002By exploiting the spatial diversity among different signals, anti-jamming communications can be accomplishing using antenna arrays. In this paper, we discuss the self-recovery problem for antenna array wireless systems after the communication link is broken due to abrupt environmental changes.

Deep Learning for an Anti-Jamming CPM Receiver
MILCOM 2019 - 2019 IEEE Military Communications Conference (MILCOM), 2019A novel continuous phase modulation (CPM) receiver model is proposed in this paper that employs deep learning (DL) techniques to improve the signal recovery and synchronization performance under heavy jamming conditions for frequency hopping (FH) based waveforms. A hybrid deep neural network is used to implement the DL in the receiver model.

Active Anti-jamming Solutions in CRNs
2015Cognitive radio nodes are motivated to perform jamming attacks, if the illegal gains exceed the payment due to the attacking cost and the loss from the resulting punishment. In this chapter, we present active anti-jamming solutions in CRNs, based on reciprocity principles, social norms and reinforcement learning techniques.

Research on Anti-Jamming RF-EAS System
Advanced Materials Research, 2014This thesis takes AIO (All-In-One) type of RF-EAS systems as the object, to study how to improve its anti-interference performance. Interference noise in the article is divided into two types, which are steady noise and transient noise. According to the characteristics of different interference noises, their impacts on all aspects of the system are ...

The Integrative Application of Anti-Jamming Technology for Radar
2010 2nd International Workshop on Intelligent Systems and Applications, 2010This paper analyzed some primary techniques of anti-jamming technology for radar. Simulation results show the merit of each method. And it proposed a new idea that combines some typical anti-jamming techniques together. It was a more effective way of the integrative anti-jamming technology.
