A signal-to-noise ratio (SNR) of the second signal is measured, and the SNR of the first signal is determined based at least in part upon the measured SNR of the second signal.
Disclosed are a method and an apparatus to estimate a signal-to-noise ratio (SNR) of a signal.
The signal-to-noise ratio is compared to a threshold signal-to-noise ratio (63).
Various sources of noise are also suppressed to further increase signal-to-noise ratio.
Various sources of noise are also suppressed to further increase signal-to-noise ratio.
The invention enables to obtain a better signal-to-noise ratio.
The signal-to-noise ratio for the interrogator receiver output signal is improved, because this signal no longer contains an amplitude noise of the interrogator transmitter.
A substraction technique preferably enhances the signal/noise ratio.
The aim of the invention is to achieve an improved signal/noise ratio when receiving radio signals in an automobile.
The summation greatly improves the SNR.
Use of noise reduction telephones leads to increase in SNR which allows greater number of users.
An improved resolution and SNR can thus be obtained.
An aggregate score may be obtained based on the feature scores according to a weighting scheme which may be associated with a noise and/or SNR estimation.
The SNR determiner (16) determines the SNR per channel of the input signal.
A noise estimator (31) derives a correlated noise signal (n1, n2) from equalized signal having the best signal to noise ratio.
This correlated noise signal (n1,n2) is used to cancel the correlated noise with another of the equalized signals, so as to improve the signal to noise ratio of that signal.
The combined response may have a signal to noise ratio larger than that of any individual response.
As a result the signal to noise ratio can be increased.
A method, apparatus and computer program for improving the signal-to- noise ratio of a signal S(t), S(t) containing Signal and noise, are disclosed.
Optical Signal to Noise ratio equal to or exceeding 103.
Optical Signal to Noise ratio equal to or exceeding 103.
Optical Signal to Noise ratio equal to or exceeding 103.
The invention maintains a predetermined signal to noise ratio.
The signal-to-noise-ratio is therefore significantly increased.
The capacitive sensor provides increased signal to noise ratio.
The pre-incubation enhances the signal to noise ratio of the assay.
The regulation is thus largely independent of the signal-noise ratio of the analogue input signal (I; Q).
Non-linear spectrum analysis can improve signal-to noise further.
The power allocation similarly decreases the bit-error rate for a given signal-to- noise ratio, especially at high signal-to-noise ratios.
