er·god·ic

 (ûr-gŏd′ĭk)
adj.
Of or relating to a system or process whose overall statistical properties can be determined by analysis of a sufficiently large sample of the states of one of its constituents or instances averaged over time.
[German Ergode, a set of points in a space with the property that all points will be included in a trajectory with equal frequency given a sufficient large number of trajectories (coined by Ludwig Eduard Boltzmann from Greek ergon, work; see werg- in Indo-European roots + Greek hodos, way, path) + -ic.]

In this section, key statistical properties of the model, e.g., the spatial cross-correlation function (CCF), temporal autocorrelation function (ACF), Wigner-Ville spectrum, and ergodic capacity under non-isotropic scattering conditions considering the impact of velocity variations will be derived.
A Non-Stationary Geometry-Based Cooperative Scattering Channel Model for MIMO Vehicle-to-Vehicle Communication Systems
Bou-Rabee and Vanden-Eijnden propose a strategy for simulating stochastic differential equations, adopting an approach that is more tailored to the probabilistic structure of the solution in order to design stable and (weakly) accurate schemes for their simulation that are both provably ergodic when the underlying stochastic differential equation is, and faithful to the geometry of their domain of integration.
