Theory and assessment of an improved power spectral density estimator [PDF]

, 1990
This thesis is concerned with the processing of time domain signals received by a single sensor. An example of such signals is the radar return, which is used in one way or another to estimate the power spectral density a frequency representation of ...

Spectral density constraints on wireless communication [PDF]

, 2020
Environmental exposure to man-made electromagnetic field (EMF) has been rising as modern technologies have grown and changed in social behaviour have generated more synthetic sources. For the safety of human health, EMF levels need to be regulated.

Power Spectral Density Error Analysis of Spectral Subtraction Type of Speech Enhancement Methods

EURASIP Journal on Advances in Signal Processing, 2007
A theoretical framework for analysis of speech enhancement algorithms is introduced for performance assessment of spectral subtraction type of methods. The quality of the enhanced speech is related to physical quantities of the speech and noise (such ...

Spectrum sensing based on cumulative power spectral density

EURASIP Journal on Advances in Signal Processing, 2017
This paper presents new spectrum sensing algorithms based on the cumulative power spectral density (CPSD). The proposed detectors examine the CPSD of the received signal to make a decision on the absence/presence of the primary user (PU) signal.

Power Spectral Density Conversions and Nonlinear Dynamics

Shock and Vibration, 1994
To predict the vibration environment of a payload carried by a ground or air transporter, mathematical models are required from which a transfer function to a prescribed input can be calculated.

Gravitational-wave astronomy with an uncertain noise power spectral density

Physical Review Research, 2020
In order to extract information about the properties of compact binaries, we must estimate the noise power spectral density of gravitational-wave data, which depends on the properties of the gravitational-wave detector. In practice, it is not possible to
