The paper aims at showing that this pulse shaping gives interesting spectral properties in the case of a cubic nonlinear power amplifier. In a second step, an original algorithm is also proposed to reduce either the peak-to-average power ratio (PAPR) or the cubic metric (CM) of the OFDM/...
Power Spectral Density Definition 2.4 Given a WSS stochastic processun, itspower spectral density(PSD) (or simply thepower spectrum) is defined as the Fourier transform of its autocorrelation sequence, (2.122) Using the Fourier transform properties, we can recover the autocorrelation sequence via the...
These spectra give a guide to the scattering properties of the surface, which in turn critically influence the performance of LIGO. Measurements obtained by use of a full-aperture interferometer and an interference microscope with two different objectives are combined to produce one-dimensional power ...
We investigate statistical properties of GRB light curves by comparing the reported characteristics in the PDSs of the observed GRBs with those that we model, and discuss implications on interpretations of the PDS analysis results. Results of PDS analysis of observed GRBs suggest that the averaged ...
The spectrum analyzer provides three units to specify the power spectral density:Watts/Hz,dBm/Hz, anddBW/Hz. Corresponding units of power areWatts,dBm, anddBW. For electrical engineering applications, you can also view the RMS of your signal inVrmsordBV. The default spectrum type isPowerindBm...
Stochasticity plays a central role in nearly every biological process, and the noise power spectral density (PSD) is a critical tool for understanding variability and information processing in living systems. In steady-state, many such processes can be described by stochastic linear time-invariant (...
The Spector and Grant method, which has been in use for 25 years, relates average depths to source to rate of decay of the magnetic power spectra. This method, which assumes a uniform distribution of parameters for an ensemble of magnetized blocks, leads to a depth-dependent exponential rate...
Spectral analysisStatistical analysisThis study presents our findings on the ferroresonance phenomenon for the Seyitomer鈥揑siklar part of the Electric Power System of 380kV in Turkey. In this context, the power spectral density approach and Short-Time Fourier Transforms are applied to the voltage ...
The properties and calculation methods of the backward transition probability are discussed. By use of this concept, a method for calculating the power spectral density (PSD) of the cyclostationary random process is derived, which is applicable to the arbitrary state pulse length. Some examples are...
The statistical properties of the density fluctuations produced by power-law inflation are investigated. It is found that, even the fluctuations present in... JD Barrow,P Coles - 《Monthly Notices of the Royal Astronomical Society》 被引量: 3发表: 1990年 Inflation from a massive scalar field ...
