Reflected Signal Bias in Biotelemetry Triangulation Systems
The Journal of Wildlife Management, 1986Accuracy of 4 3-tower triangulation systems was quantified using surveyed reference points. All reference points within line-of-sight (LOS) of towers produced accurate and precise bearings, but 52% of points non-line-of-sight (NLOS) to towers produced inaccurate and/or imprecise bearings due to reflected radio signals.

Ranging Bias of COMPASS Satellite Signals
2015Quantitative evaluation of signal quality of navigation satellites in orbit is one of the difficulties in satellite navigation signal quality monitoring research, so a quantitative evaluation method based on theoretic ranging bias is proposed. Based on Vernier sampling principle and a large diameter parabolic antenna is used for in-orbit satellite ...

Conflict, receiver bias and the evolution of signal form
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1995In a model, conflicts of interest between communicating individuals are shown to have an important influence on the cost and form of signals that evolve. Two types of conflict are considered: competition between senders to obtain a response from the receiver, and conflict between the sender and the receiver.

Visual signals bias auditory targets in azimuth and depth
Experimental Brain Research, 2011In the psychophysical phenomenon visual bias, an accurately localized irrelevant signal, such as a light, impairs localization of a spatially discrepant target, such as a sound, when the two stimuli are perceived as unified. Many studies have demonstrated visual bias in azimuth, but none have tested directly or found this effect in depth.

Signal bias removal based GMM for robust speaker recognition
IIEEE International Conference on Acoustics Speech and Signal Processing, 2002In this paper, we focus on the combined method of SBR and GMM-UBM and its capacity for detection and robustness of speaker recognition. While each method has achieved improvements independent of each other in an orthogonal field, both methods have a similar framework. The proposed Signal Bias Removal based GMM (SBR-GMM) executes the minimization of the

How orexin signals bias action: Hypothalamic and accumbal circuits
Brain Research, 2020Survival-maximizing, well-timed actions are a key responsibility of the brain. Hypothalamic neurons containing neurotransmitters orexins/hypocretins are important players in this process. Individuals without orexin neurons display inappropriately-timed transitions between arousal states, and other behavioural abnormalities including increased risk ...

Bounds on the Bias of Signal Parameter Estimators
Bell System Technical Journal, 1969Any estimator which is constrained to take values in a finite range is, in general, biased. Many times the bias is unknown; furthermore, in some cases the bias may become the main contributor to the mean square error of an estimator. This paper derives upper and lower bounds on the bias of a finite-range, signal parameter estimator.

Systematic Phase Retrieval Error Due to Signal Bias
Frontiers in Optics, 2006Signal bias in measured PSFs can cause systematic errors in the retrieved phase for the generalized pupil function of an optical system. We discuss the nature of these errors and compensation methods.
