Multiple coherence function
WebBy use of path-integral methods, a general expression is obtained for the two-frequency, two-position mutual coherence function of an electromagnetic pulse propagating through turbulent atmosphere. This expression is valid for arbitrary models of refractive-index fluctuations, wide band pulses, and turbulence of arbitrary strength. WebMultiple Coherence and Ordinary Coherence Generate a random two-channel signal, x. Generate another signal, y, by lowpass filtering the two channels and adding them …

Web19 mar. 2024 · The two-frequency mutual coherence function can be used to investigate the laser pulse scattering characteristics of arbitrarily shaped rough objects, provide theoretical basis for target recognition. WebCoherence is an ideal property of wavesthat enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but …
WebThe mutual coherence function (MCF) is used to analyze the distortion that electromagnetic waves suffer when they propagate through such a medium. In this paper, we analyze the MCF in two dimensions for an incoherent line source. WebTemporal cohesion is when parts of a module are grouped by when they are processed - the parts are processed at a particular time in program execution (e.g., a function which is called after catching an exception which closes open files, creates an error log, and notifies the user). Procedural cohesion

In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate … Vedeți mai multe The coherence (sometimes called magnitude-squared coherence) between two signals x(t) and y(t) is a real-valued function that is defined as: $${\displaystyle C_{xy}(f)={\frac { G_{xy}(f) ^{2}}{G_{xx}(f)G_{yy}(f)}}}$$ where … Vedeți mai multe Here we illustrate the computation of coherence (denoted as $${\displaystyle \gamma ^{2}}$$) as shown in figure 1. Consider … Vedeți mai multe Coherence has been found a great application to find dynamic functional connectivity in the brain networks. Studies show that the coherence between different brain … Vedeți mai multe If the signals are non-stationary, (and therefore not ergodic), the above formulations may not be appropriate. For such signals, the concept of coherence has been extended by using the concept of time-frequency distributions to represent the time … Vedeți mai multe • Bicoherence • Scaled Correlation • Normalized cross-correlation Vedeți mai multe meaning of jadonWebMultiple-input multiple-output (MIMO) is a promising technique to realize tremendous rise in the demand for wireless data traffic in future generation of wireless systems.
