Opportunistic Power Control for Low Probability of Detection Communication
MILCOM 2022 - 2022 IEEE Military Communications Conference (MILCOM), 2022Power control strategies are widely used in wireless networks to minimize transmit power and manage interference. On fading channels that vary with time, however, power control can occasionally lead to high transmit powers that make the transmitter easy ...

Emulating Low Probability of Detection Algorithms
2020 30th International Telecommunication Networks and Applications Conference (ITNAC), 2020Software Defined Radios (SDRs) can be used to create and modify radio waveforms in order to perform research into various wireless network problems. Defence Science and Technology Group (DSTG) has created the Experimental Framework of SDRs (EFOS) incorporating bespoke SDRs communicating with one another through an RF attenuation matrix.

Minimising RF Detectability for Low Probability of Detection Communication
2018 Military Communications and Information Systems Conference (MilCIS), 2018This paper describes the need for management of transmission powers in mobile land networks in order to achieve low probability of detection. It explores applicable work in topology control and presents sub-graph search, a localized search method for finding the topology with the lowest detectability footprint.

Chaos for low probability of detection communications
Chaos, Solitons & Fractals, 2017Abstract Many methods for using chaos as a communications signal have been suggested, but all suffer from the difficulty in synchronizing the transmitter and receiver. Chaotic signals are broad band and unpredictable, making them potentially useful when the goal is low interference communications or even low probability of detection (LPD ...

Low probability of detection for underwater acoustic communication
2014 Oceans - St. John's, 2014The ability to avoid detection of a communication signal in the underwater acoustic channel is extremely important for underwater acoustic communication (UWAC) systems when used for military-related applications. Furthermore, low probability of detection (LPD) may reduce environmental impact of UWAC as communication signals can be transmitted at lower ...

Low probability of detection communications-LPD waveform design and detection techniques
MILCOM 91 - Conference record, 2002The author defines six typical conventional and low probability of detection (LPD) waveforms and analyzes them against seven detection techniques. Simplified models are presented as examples of each technique and approximate sensitivities derived. These provide a general approach to the designing of waveforms that successfully resist detection.

Bounds for Low Probability of Detection for Underwater Acoustic Communication
IEEE Journal of Oceanic Engineering, 2016Most military underwater activities require stealth operations, and hydroacoustic transmissions might temper the mission. For this reason, military underwater acoustic transmission aims for low probability of detection (LPD). LPD communication systems are characterized by low transmission power and reception at low signal-to-noise power ratio (SNPR ...
