1.A 3D statistical channels model for mobile frequency selective fading MIMO channels was proposed and a new joint space-time-frequency correlation function was derived.针对频率选择性衰落MIMO移动信道,建立三维(3D)纯随机模型,并推导出3D MIMO信道模型的联合空时频相关函数。 3)time-space correlation functi...
The relevant space-time correlation function for a reaction of type A + M → B + C is a one-particle Green's function describing creation and propagation of an "M hole".doi:10.1016/0009-2614(86)87172-XM.D. GirardeauC.I. Ivanov
Cross sections for atomic or molecular reactive scattering from a medium are expressed in terms of space-time correlation functions of the medium and transition amplitudes for individual reactive collisions. Among the physical effects included thereby are energy and momentum transfer to the medium. The...
Space-time correlation functions constitute a useful instrument from the research toolkit of continuous-media and many-body physics. Here we adopt this concept for single-particle random walks and demonstrate that the corresponding space-time velocity autocorrelation functions reveal correlations which exten...

The chief points of this method are the applications of the theory of random time-varying networks and the theory of streams of random events in queueing theory. An expression of space-time correlation function of scattered fields is established by this method. More factors, such as the random...
First, it examines how the smoothness away from the origin of a spacetime covariance function affects, for example, temporal correlations of spatial differences. Models that are not smoother away from the origin than they are at the origin, such as separable models, have a kind of discontinuity...
Hydrodynamics and Time-Correlation Functions The derivation of hydrodynamic equations, and their constitutive relations, by the time-correlation function method requires the reduction of general nonlocal equations to the usual local differential equations. This is accomplished by a......
As a result, each spatial frequency kx is associated with a single temporal frequency ω, with a delta-function correlation whose functional form depends on θ, kx = kx(ω, θ)42,70. Consequently, the envelope ψ(x, z, t) of the wave packet \(E(x,z,t)={e}^{i({k}_{{\...
