Demo abstract: An anti-jamming wireless communication system

IEEE INFOCOM 2018 - IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2018
This demonstration presents a real-time anti-jamming MIMO-OFDM wireless communication system that consists of a transmitter, a receiver, and a high-power wideband radio jammer. The key component of our system is a new PHY design for the receiver, which can mitigate jamming signal and recover the desired signal.

Design and Implementation of Antenna Anti-Jamming Communication

2019 International Conference on Smart Grid and Electrical Automation (ICSGEA), 2019
Traditional square antenna anti-jamming communication is prone to errors, resulting in rapid deterioration or even failure of communication performance. Therefore, the anti-jamming RF front-end system based on antenna array is optimized, and the multi-channel antenna signal acquisition algorithm is designed to solve the problem that traditional antenna

Blind Source Separation for Satellite Communication Anti-jamming

2019
In this paper, the feasibility of applying blind source separation (BSS) to satellite communication (SatCom) anti-jamming is studied. And an EASI-based BSS method is introduced for anti-jamming processing for SatCom system. This method achieves the elimination of jamming signal by separation.

Research and Implementation of Anti-Jamming Technology for Wireless Data Communication

2014 IEEE International Conference on Computer and Information Technology, 2014
In 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 ...

(T, ∊)-Greedy Reinforcement Learning for Anti-Jamming Wireless Communications

GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020
In 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 ...

Power control Stackelberg game in cooperative anti-jamming communications

The 2014 5th International Conference on Game Theory for Networks, 2014
As wireless networks are vulnerable to malicious attacks, security issues have aroused enormous research interest. In this paper, we focus on the anti-jamming power control of transmitters in a cooperative wireless network attacked by a smart jammer with the capability to sense the ongoing transmission power before making a jamming decision.

Research on Intelligent Anti-jamming Communication with Transform Domain Communication System

2019
In 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

An Anti-jam Communications Technique via Spatial Hiding Precoding

2014 IEEE Military Communications Conference, 2014
This 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.

Power control games for multi-user anti-jamming communications

Wireless Networks, 2018
This 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.

Design of an anti-jamming Appliqué for LTE-based military communications

MILCOM 2016 - 2016 IEEE Military Communications Conference, 2016
The United States Department of Defense (DoD) is contemplating the use of commercial technologies such as 4G/LTE (Long Term Evolution) for tactical edge communications because of several benefits offered by them. However, the greatest hindrance to the adoption of LTE for military communications is its lack of support to combat the presence of malicious
