Jamming/anti-jamming game with a cognitive jammer in space communication
SPIE Proceedings, 2012In this paper a basic cognitive jamming/anti-jamming problem is studied in the context of space communication. The scenario involves a pair of transmitter and receiver, and a cognitive jammer. The cognitive jammer is assumed to have powerful spectrum sensing capability that allows it to detect data transmission from the transmitter to the receiver ...

QPSO-Based Beamforming in Dual RIS-Assisted Uplink Anti-Jamming Communication System
International Conference on Advanced Communication TechnologyConsidering a dual reconfigurable intelligent surface (RIS) assisted uplink cellular communication system under a malicious jamming user with known positions, we propose a joint active and passive anti-jamming beamforming scheme to maximize the system ...

Power control games for multi-user anti-jamming communications
Wireless Networks, 2018This paper investigates two different anti-jamming scenarios for wireless networks in which there exist one jammer and multiple users. The jammer jams all the users simultaneously. In one scenario, the users and the jammer sense the opponent’s information, and take appropriate strategies accordingly.

An adaptive-rate anti-jam system for optimal voice communication
MILCOM 97 MILCOM 97 Proceedings, 2002Systems for the digital transmission of voice have traditionally been fixed rate in anti-jam situations. This design severely limits the potential of the communication system in the case of voice since compression of speech is a lossy process. Bit errors in the transmission of voice coded speech cause degradation which can be compensated for in several

Research and Implementation of Anti-Jamming Technology for Wireless Data Communication
2014 IEEE International Conference on Computer and Information Technology, 2014In order to solve the problem that the data which get from the load on the machine is vulnerable to be interrupt when it transmission by the wireless communication, making the GCS (ground control system) can not receive properly. By analyzing the link transmission error model of the downstream data, design and implement an efficient erasure coding ...

An anti-jamming improvement strategy for satellite frequency-hopping communication
2009 International Conference on Wireless Communications & Signal Processing, 2009Satellite frequency-hopping (FH) communication for anti-jamming was studied. Effects of jamming on frames that belongs to the link layer were analyzed. A measurement, link frame throughput was proposed. In addition, a time-frequency diversity strategy was suggested to improve anti-jamming performance of the system on the measurement of link frame ...

Research on Intelligent Anti-jamming Communication with Transform Domain Communication System
2019In order to solve the interference problem in a complex electromagnetic environment, NC-OFDM and TDCS are efficient transmit waveform. The spectral efficiency and the applicable environment of TDCS are different from NC-OFDM. The simulation results show that NC-OFDM can obtain the higher spectral efficiency and the required SINR is higher, and TDCS can

Modeling and Simulation of Frequency Hopping Anti-jamming Communication System
2010 Second International Conference on Modeling, Simulation and Visualization Methods, 2010With the better capabilities of anti-jamming, low-probability of interception and networking, frequency hopping communication is one of the most widely used technologies at present. In order to study and validate the anti-jamming capability of FH communication system, it is urgently needed to establish a high efficiency simulation platform.

An Anti-jam Communications Technique via Spatial Hiding Precoding
2014 IEEE Military Communications Conference, 2014This work describes a new method of designing an anti-jam communications system. The key insight is that many of the concepts learned from interference alignment (IA) in multiple antenna (MIMO) systems can be applied to the field of antijam and robust communications in the presence of intentional jammers.
