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.

Refined PHD Filter for Multi-Target Tracking under Low Detection Probability
Sensors, 2019 Radar target detection probability will decrease as the target echo signal-to-noise ratio (SNR) decreases, which has an adverse influence on the result of multi-target tracking.

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}(

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
