Fundamental limits of optical microrheology.
We estimate the fundamental limits of different microrheological techniques based on optical detection. It is suggested that particle tracking systems using nondifferential detection have a minimum detectable displacement given by 0.2(lambda0/NA)(1/square root of (SNR)), where lambda0 is the wavelength, NA is the numerical aperture of the focusing objective, and SNR is the signal-to-noise ratio...

Nowadays, several infrastructure-based low-frequency acoustical sensor networks are employed in different applications to monitor the activity of diverse natural and man-made phenomena, such as avalanches, earthquakes, volcanic eruptions, severe storms, super-sonic aircraft flights, etc. Two signal detection methods are usually implemented in these networks for the purpose of event occurrence i...
متن کاملA Novel Multi-user Detection Approach on Fluctuations of Autocorrelation Estimators in Non-Cooperative Communication
Recently, blind multi-user detection has become an important topic in code division multiple access (CDMA) systems. Direct-Sequence Spread Spectrum (DSSS) signals are well-known due to their low probability of detection, and secure communication. In this article, the problem of blind multi-user detection is studied in variable processing gain direct-sequence code division multiple access (VPG D...
متن کاملAccurate detection of low signal-to-noise ratio neuronal calcium transient waves using a matched filter.
BACKGROUND Calcium imaging has become a fundamental modality for studying neuronal circuit dynamics both in vitro and in vivo. However, identifying calcium events (CEs) from spectral data remains laborious and difficult, especially since the signal-to-noise ratio (SNR) often falls below 2. Existing automated signal detection methods are generally applied at high SNRs, leaving a large need for a...
متن کاملBounds on Time Delay and Doppler Estimation with Partially Coherent Signals
Fundamental performance limits for passive time delay and Doppler estimation have been studied extensively for several decades. The fundamental limits are usually parameterized in terms of the signal-to-noise ratio (SNR) at each sensor, the spectral support of the signals (fractional bandwidth), and the time-bandwidth product of the observations. In some applications, loss of coherence between ...
