The signal-to-noise ratios (SNRs) of three Gaussian-state ghost imaging\nconfigurations--distinguished by the nature of their light sources--are\nderived. Two use classical-state light, specifically a joint signal-reference\nfield state that has either the maximum phase-insensitive or the maximum...
Furthermore, the performance loss of one-bit radar detectors proposed in [12] is only 2 dB (π/2) at low signal-to-noise ratios (SNRs), which can be compensated via increasing the number of samples by a factor π/2. These merits motivate the application of one-bit sampling techniques ...
Phase-stepping(PS) is a widely used method to retrieve information, while angular signal radiography(ASR) is a newly established method. In this manuscript,signal-to-noise ratios(SNRs) of ASR are compared with that of PS. Numerical experiments are performed to validate theoretical results. SNRs ...
A post-processing technique to estimate the signal-to-noise ratio and remove echosounder background noise A simple and effective post-processing technique to estimate echosounder background-noise levels and signal-to-noise ratios (SNRs) during active pinging is... DR Alex,H Ian - 《Ices J.mar...
The authors compared the signal-to-noise ratios (SNRs) of nerve recordings obtained with an open cuff (a 270° cylinder) and a full cylindrical electrode (simulated by lifting the open electrode outside the solution) using an in vitro set-up. The thermal noise was considered as the main so...
The speech intelligibility in classroom can be influenced by background-noise levels, speech sound pressure level (SSPL), reverberation time and signal-to-noise ratio (SNR). The relationship between SSPL and subjective Chinese Mandarin speech intelligibility and the effect of different SNRs on Chinese...
The signal-to-noise ratios (SNRs) of these methods are theoretically calculated in terms of transducer bandwidth, PA signal generation physics, and laser pulse or chirp parameters. Large differences between maximum (peak) SNRs were predicted. However, it is shown that in practice the SNR ...
Speech separation is a challenging problem at low signal-to-noise ratios (SNRs). Separation can be formulated as a classification problem. In this study, we focus on the SNR level of -5 dB in which speech is generally dominated by background noise. In such a low SNR condition, extracting...
