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 communication is low.

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 ...

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 presence of the transmitter or receiver.

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 ...

Detectability models for multiple access low-probability-of-intercept networks [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2000 Increased demands for communications in the tactical battlefield have driven the development of multiple access low-probability-of-intercept (LPI) networks. Most detectability studies of LPI networks focus on the individual links of the network, in which the intercept and detectability calculations are conducted for a single network transmitter.

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.

Quantum-noise limited communication with low probability of detection
CoRR, 2014 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. Specifically, Alice can transmit $\mathcal{O}(

A New Noncoherent Gaussian Signaling Scheme for Low Probability of Detection Communications
IEEE Wireless Communications Letters, 2023 We propose a novel, Gaussian signaling mechanism for low probability of detection (LPD) communication systems with either single or multiple antennas. The new scheme is designed to allow the noncoherent detection of Gaussian-distributed signals, enabling LPD communications using signals that follow the complex Gaussian distribution in the time and ...
