This paper studies sub-classes of two-user fast fading Gaussian interference channels (GIC) with ergodic strong/very strong interference, for which channel state information (CSI) is only available at the receivers. Under this setting, the ergodic capacity region is open. In this work we derive a sufficient condition for ergodic strong/very strong GIC to achieve the ergodic capacity regions by stochastic ordering with same marginal property. We also illustrate examples to show the usage scenarios of the derived conditions.
