Abstract

In this talk, we will explore the capacity and generalized degrees of freedom (GDOF) of the two-user Gaussian X channel, i.e., a generalization of the two-user interference channel where there is an independent message from each transmitter to each receiver. First, we will characterize the sum capacity of the deterministic X channel under a symmetric setting. Then, we will characterize the GDOF of the Gaussian X channel under a similar symmetric model. Finally, we will extend the sum capacity characterization previously obtained for the Gaussian interference channel in the noisy interference regime to the Gaussian X channel. Specifically, we will show that the Gaussian X channel has the same sum capacity as the underlying Gaussian interference channel in this regime.
