signals with relatively small length, the filter bank approach produces a spectral estimate with a higher resolution, a more accurate noise floor, and peaks more precise than the Welch method, with low or no spectral leakage. These advantages come at the expense of increased computation and ...
spectral analysis.p/ pThe majority of the nonlinearity in a communication system is attributed to the power amplifier (PA) present at the final stage of the transmitter chain. In this paper, we consider Gaussian distributed input signals (such as OFDM), and PAs that can be modeled by ...

It is used for filtering, spectral analysis, complexity reduction, equalization and so many other kinds of analysis. In this article, we are going to illustrate the properties of the discrete Fourier Transform which are different from the conventional, time-continuous Fourier transform. We will...

In the context of LIDAR, spectral analysis can be used for environmental monitoring. See also the article on spectroscopy for more applications. Depending on the application, the requirements concerning the covered wavelength region, the performance (e.g. resolution, sensitivity, speed, etc.) and ...

Rather than using the sine formulation of the Fourier Transform, a wavelet formulation can be used instead. This can address some of the time-frequency tradeoffs. See the knowledge base articleTime-Frequency Analysis: Wavelets. 4.Simcenter Testlab Settings ...

the search space for this analysis was restricted to auditory, ventral premotor and inferior frontal regions25in both hemispheres (see methods for details). Spectral control (orange in Fig.3b) was associated with increased activity in a cluster of voxels in the right inferior frontal gyrus (IFG)...
