Anti-jamming Technology in Small Satellite Communication

Simulation of Anti-Jamming Technology in Frequency-Hopping Communication System

Frequency-hopping communication is widely used in the field of military communication, which has the capability to resist interference. In frequency-hopping system, narrowband interference signals exist in partial dehopping frequency-hopping signals, equivalent to time-varying interference signals existed in the frequency-hopping signals. Through integrating the diversity combining with singula...

Rendezvous Protocols and Dynamic Frequency Hopping Interference Design for Anti-jamming Satellite Communication

Analysis of Anti-Jamming Techniques for Satellite Navigation Systems

GNSS(Global Navigation Satellite System) is now being widely used in both civilian and military applications where accurate positioning and timing information are required and it is considered as a representative convergence technique in IT-Military application techniques. However, GNSS has low sensitivity level of GNSS receivers and is vulnerable to jamming signal, since the signals come from ...

Compromise-resilient anti-jamming communication in wireless sensor networks

Jamming is a kind of Denial-of-Service attack in which an adversary purposefully emits radio frequency signals to corrupt the wireless transmissions among normal nodes. Although some research has been conducted on countering jamming attacks, few works consider jamming attacks launched by insiders, where an attacker first compromises some legitimate sensor nodes to acquire the common cryptograph...

Towards Optimal UFH-based Anti-jamming Wireless Communication

Anti-jamming communication without pre-shared secrets has gained increasing research interest recently and is commonly tackled by utilizing the technique of uncoordinated frequency hopping (UFH). Existing researches, however, are almost all based on ad hoc designs of frequency hopping strategies, mainly due to lack of theoretical foundations for scheme performance evaluation. To fill this gap, ...
