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 the … See more 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 Gxy(f) is the See more Here we illustrate the computation of coherence (denoted as $${\displaystyle \gamma ^{2}}$$) as shown in figure 1. Consider the two signals shown in the lower portion of figure 2. There appears to be a close relationship between the ocean surface water … See more • Bicoherence • Scaled Correlation • Normalized cross-correlation See more If the signals are non-stationary, (and therefore not ergodic), the above formulations may not be appropriate. For such signals, the … See more Coherence has been found a great application to find dynamic functional connectivity in the brain networks. Studies show that the coherence between different brain regions can … See more WebCoherence clusters consist of multiple Managed Coherence server instances that distribute data in-memory to increase application scalability, availability, and performance.
