Widespread preprocessing techniques for resolving the coherent source localization problem are the forward-backward averaging and the spatial smoothing [22, 23, 25].
In 1972, Kon and Tatarskii considered the MCF of a partially coherent source in a turbulent medium and investigated the dependence of the average light intensity in turbulent medium on the initial degree of coherence of the source [10].
Especially after the introduction of free-space optical atmospheric communication links, the average BER can be significantly reduced by the use of a partially coherent source beam.
One such solution is Integrated Quality Management (IQM), which bridges the gap between NPDI and quality management processes, and enables a coherent source of truth and management of new product development as well as quality related data.
Supercontinuum generation in microstructure fiber has the potential of providing an extremely broadband, very bright, spatially and phase coherent source; these supercontinua already have revolutionized the field of optical frequency metrology.
When waves come from a coherent source such as a laser, all their peaks and troughs line up exactly.
The editors' goal was to create a focused, systematic, thorough, and stimulating book that will serve as a cohesive and coherent source of information on law-related education in juvenile justice.
To create a coherent source that can be modulated to simulate pulse compression, linear FM and FM on pulse requires a special synthesized source to be designed.
A phase coherent source will predictably have maximum periodic peak voltage swings.
Without loss of generality, the impinging source [{[s.sub.k](t)}.sup.K.sub.k=1] is a mixture of uncorrelated and coherent sources. Note that there exists power fading among the coherent source, and fading coefficients are used to describe the degree of power fading [5].
In two-center-model of H2[?], each atom act as a coherent source of electron waves and separated by small distance d called bond-length or equilibrium distance.
