Fundamental Limits of Communication with Low Probability of Detection [PDF]
IEEE Transactions on Information Theory, 2016 This paper considers the problem of communication over a discrete memoryless channel (DMC) or an additive white Gaussian noise (AWGN) channel subject to the constraint that the probability that an adversary who observes the channel outputs can detect the

Low Probability of Detection for Underwater Acoustic Communication: A Review [PDF]
IEEE Access, 2018 Low probability of detection (LPD) is an extremely important characteristic of an underwater acoustic communication (UWAC) system when used for military-related applications, since the detection of a communication signal in the channel may reveal the ...

High-Resolution, Low Probability of Detection Links Through SDRs
IEEE Journal of MicrowavesThis paper presents the design and implementation of a low probability of detection (LPD) communication link using a software-defined radio (SDR) platform. The proposed LPD link was tested in an indoor environment using an over-the-air (OTA) network. The

Target Tracking While Jamming by Airborne Radar for Low Probability of Detection [PDF]
Sensors, 2018 Although radiation power minimization is the most important method for an advanced stealth aircraft to achieve the low probability of detection (LPD) performance against the opposite passive detection system (PDS), it is not always effective when the ...

Superimposed training low probability of detection underwater communications [PDF]
The Journal of the Acoustical Society of America, 2020 This paper proposes a superimposed training method for low probability of detection underwater acoustic communications. A long pilot sequence was superimposed to the message for equalization and synchronization purposes. A fast Hadamard transform (FHT) estimated the channel impulse response and compressed the pilot energy.

Low Probability of Detection Communication: Opportunities and Challenges [PDF]
IEEE Wireless Communications, 2019 Low probability of detection (LPD) communication has recently emerged as a new transmission technology to address privacy and security in wireless networks. Recent studies have established the fundamental limits of LPD communication in terms of the amount of information bits that can be conveyed from a transmitter to a receiver subject to a constraint ...

Using areas of known occupancy to identify sources of variation in detection probability of raptors: taking time lowers replication effort for surveys [PDF]
Royal Society Open Science, 2016 Species occurring at low density can be difficult to detect and if not properly accounted for, imperfect detection will lead to inaccurate estimates of occupancy.

Analysis of the low-probability-of-detection characteristics of ultraviolet communications
Optics Express, 2020 Deep ultraviolet wavelengths have been proposed for low-probability-of-detection (LPD) communications, particularly for non-line-of-sight (NLOS) links, because of the increased atmospheric absorption at these wavelengths. Motivated by this favorable feature, we develop a modeling framework to quantitatively study the LPD characteristics of ultraviolet ...

Limits of Reliable Communication with Low Probability of Detection on AWGN Channels [PDF]
IEEE Journal on Selected Areas in Communications, 2013 We present a square root limit on the amount of information transmitted reliably and with low probability of detection (LPD) over additive white Gaussian noise (AWGN) channels. Specifically, if the transmitter has AWGN channels to an intended receiver and a warden, both with non-zero noise power, we prove that $o(\sqrt{n})$ bits can be sent from the ...

Quantum noise limited optical communication with low probability of detection [PDF]
2013 IEEE International Symposium on Information Theory, 2013 We demonstrate the achievability of a square root limit on the amount of information transmitted reliably and with low probability of detection (LPD) over the single-mode lossy bosonic channel if either the eavesdropper's measurements or the channel itself is subject to the slightest amount of excess noise.
