On Wiener Phase Noise Channels at High Signal-to-Noise Ratio
, 2013 Consider a waveform channel where the transmitted signal is corrupted by Wiener phase noise and additive white Gaussian noise (AWGN). A discrete-time channel model that takes into account the effect of filtering on the phase noise is developed. The model

Noise Folding in Compressed Sensing [PDF]
, 2011 The literature on compressed sensing has focused almost entirely on settings where the signal is noiseless and the measurements are contaminated by noise. In practice, however, the signal itself is often subject to random noise prior to measurement.

Improved Radar Detection of Small Drones Using Doppler Signal-to-Clutter Ratio (DSCR) Detector
Drones, 2023 The detection of drones using radar presents challenges due to their small radar cross-section (RCS) values, slow velocities, and low altitudes. Traditional signal-to-noise ratio (SNR) detectors often fail to detect weak radar signals from small drones ...

Measuring the signal-to-noise ratio of a neuron [PDF]
Proceedings of the National Academy of Sciences, 2015 SignificanceNeurons represent both signal and noise in binary electrical discharges termed action potentials. Hence, the standard signal-to-noise ratio (SNR) definition of signal amplitude squared and divided by the noise variance does not apply. We show that the SNR estimates a ratio of expected prediction errors.

Bounds on Portfolio Quality [PDF]
, 2014 The signal-noise ratio of a portfolio of p assets, its expected return divided by its risk, is couched as an estimation problem on the sphere. When the portfolio is built using noisy data, the expected value of the signal-noise ratio is bounded from ...

Non orthogonal multiple access with wind energy harvesting
Alexandria Engineering Journal, 2023 In this paper, we derive the performance of wireless communications using wind energy harvesting. We study the single-user and multi-user scenarios using Non Orthogonal and Orthogonal Multiple Access (NOMA and OMA).

Observation of Stochastic Resonance in Percolative Josephson Media [PDF]
, 2002 Measurements of the electrical response of granular Sn-Ge thin films below the superconducting transition temperature are reported. The addition of an external noise to the magnetic field applied to the sample is found to increase the sample voltage ...

Enhancing qubit readout through dissipative sub-Poissonian dynamics
, 2017 Single-shot qubit readout typically combines high readout contrast with long-lived readout signals, leading to large signal-to-noise ratios and high readout fidelities.
