The spectral density function of stochastic generalized coordinates is defined as:
It is shown that signals transmitted from specific users can be differentiated by using cyclic autocorrelation and spectral density functions characteristics.
Noise bins represent the noise by the average spectral density in two polarizations using a coarse spectral resolution.
It also features low-noise spectral density for diversity radio and I/Q demodulation systems, while consuming half of the power, when compared to alternative solutions.
Several monitor points as depicted in Figure 5 have been set on the symmetry plane to calculate the power spectral density of fluctuant velocity through spectral analysis.
Power spectral density (PSD) exhibits the strength of an energy in terms of frequency.
The structure of such controls depends on the statistical characteristics of stochastic loads--correlation function and spectral density.
While for frame/body mounted components, due to the random nature of the loading, fatigue analysis is generally accomplished in two ways: the time series approach or the spectral method based on the power spectral density of the load inputs.
The power spectral density is an important parameter of fluctuating wind and is used to describe the energy distribution of the turbulence over different frequencies.
