LNA noise parameter measurement
2015 European Conference on Circuit Theory and Design (ECCTD), 2015Joint measurement of stochastic parameters of a low noise amplifier (LNA), based on output power measurement for input termination impedances is considered. As an advantage of this method the noise parameters can be determined in a quick way for narrow and broad band applications without special equipment.

Noise Enhanced Parameter Estimation
IEEE Transactions on Signal Processing, 2008This paper investigates the phenomenon of noise enhanced systems for a general parameter estimation problem. When the estimator is fixed and known, the estimation performance before and after the addition of noise are evaluated. Performance comparisons are made between the original estimators and noise enhanced estimators based on different criteria ...

Parameter estimation in chaotic noise
IEEE Transactions on Signal Processing, 1996The problem of parameter estimation in chaotic noise is considered in this paper. Since a chaotic signal is inherently deterministic, a new complexity measure called the phase space volume (PSV) is introduced for estimation instead of using the conventional probabilistic measures.

Thermal Noise in MOSFETs: A Two- or a Three-Parameter Noise Model?
IEEE Transactions on Electron Devices, 2010In this brief, it is clearly demonstrated that a two-parameter noise model is sufficient to accurately extract the MOSFET high-frequency noise performance, as long as channel uniformity is ensured (which corresponds to mainstream CMOS technology). Nevertheless, in the case of asymmetric channel-based MOSFETs, it is shown that a three-parameter noise ...

On the Estimation of the Parameters of a Real Sinusoid in Noise
IEEE Signal Processing Letters, 2017We propose and comprehensively analyze a computationally efficient algorithm to estimate the parameters of a real sinusoidal signal in noise. This method uses the fast Fourier Transform and is, therefore, computationally efficient. Accounting for the interference due to the negative spectral component allows the frequency to be estimated very ...

On Parameter Estimation in the Presence of Noise
Theory of Probability & Its Applications, 1985In this paper the author gives practically useful and computationally efficient closed-form expressions for estimators of the parameter \(\alpha\) in the stochastic differential equation \[ d\theta (t)=-\alpha \theta (t)dt+c_ 1dw_ 1(t),\quad t\geq 0. \] The estimator is based on observations of \(\xi\), where \(\xi =\theta +\epsilon\) and \(d\epsilon ...

Parameter estimation for a burst-noise channel
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991The authors describe the estimation of the parameters of the Gilbert and Gilbert-Elliott models for burst-noise channels. Two estimation techniques are compared. The first estimation technique was proposed by Gilbert (1960) and is found to yield good estimates of the model parameters when the error sequences are long.

Verification of Noise-Parameter Measurements and Uncertainties
IEEE Transactions on Instrumentation and Measurement, 2011We propose and implement verification methods for measurements of the noise parameters of amplifiers and transistors. Because the verification rests on the comparison of different measurement results, it also serves as a test of the uncertainties. The verification process consists of first measuring separately both a passive two-port device and the ...

Virtual test of noise and jitter parameters
Proceedings International Test Conference 1996. Test and Design Validity, 2002Virtual test has proven its enormous advantages for test development, yet the use of deterministic simulation models prevented reproduction of statistical effects. This paper introduces a virtual test concept that includes noise and jitter phenomena.

Noise reduction on speech codec parameters
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004The transmission of speech in mobile or packet networks requires the use of a speech codec. In order to improve the quality of speech in a noisy environment, a noise reduction algorithm is used. This noise reduction can either be done as pre-processing before speech encoding or in the network by decoding the bitstream, performing the speech enhancement
