Anti-jamming MTI radar using variable pulse-codes
… radar is vulnerable to advanced repeat-back jamming techniques. Rapidly advancing technology producing inexpensive, high performance commercial off-the-shelf (COTS) components enable the construction of an electronic countermeasure (ECM) system capable of exploiting this vulnerability. This …

From Vulnerability to Resilience: Securing Signal Transmission Against Jamming and Spoofing Attacks
… modern communication, but its susceptibility to jamming and spoofing attacks remains a major concern. These attacks have the potential to disrupt vital services, mislead devices, and compromise the integrity of wireless systems. Many researchers have addressed anti-jamming and anti-spoofing …

Experimental Investigation Of Ultrawideband Wireless Systems: Waveform Generation, Propagation Estimation, And Dispersion Compensation
… to fading, large channel capacity and strong anti-jamming ability, there are a number of practical challenges which are topics of current research. One key challenge is the increased multipath dispersion which results because of the fine temporal resolution. The received response consists of …

Analysis of Jamming-Vulnerabilities of Modern Multi-carrier Communication Systems
… have tried hard to continuously analyze the jamming threats and come up with improved countermeausres. In this research, we have analyzed the jamming-vulnerabilities of the leading multi-carrier communication systems, Orthogonal Frequency Division Multiplexing (OFDM) and Single-Carrier …

Intelligent Approaches for Communication Denial
… against attacks from malicious nodes (e.g., anti-jamming), while significantly less work has been devoted to the equally important task of designing effective strategies for denying communication between enemy nodes/radios within an area (e.g., jamming). Such denial techniques are especially …

Improving the robustness of GPS direct position estimation
… in urban environments, while potential jamming and spoofing attacks disrupt GPS time synchronization in critical infrastructures. We propose using Direct Position Estimation (DPE), augmented with additional navigation information, to enable robust GPS receiver operation in challenging …

A jam-resistant CubeSat communications architecture
… on the space terminal. Beam-forming provides anti-jamming capabilites due to the spacings between elements in the array, also known as spatial diversity. This spatial diversity allows spatial filtering to occur, which modifies the array's radiation pattern to mitigate interference, add gain to …

User-Centric resource allocation through a power-efficient jamming-proof RAN on top of a multi-tenant backhaul
… into account, by proposing a power-efficient and jamming-proof resource allocation scheme for the RAN. Furthermore, we consider the relevant and emerging case where the backhaul is shared among different tenants. Accordingly, we exploit Software Defined Networks (SDNs) and Network Function …
