The Generalized Degrees of Freedom Region of the MIMO Z-Interference Channel With Delayed CSIT

Abstract: The generalized degrees of freedom (GDoF) region of the multiple-input multiple-output (MIMO) Gaussian Z-interference channel with an arbitrary number of antennas at each node is established under the assumption of delayed channel state information at transmitters (CSIT). The GDoF region is parameterized by α, which links the interference-to-noise ratio (INR) to the signal-to-noise ratio (SNR) via INR = SNR α . A new outer bound for the GDoF region is established by maximizing a bound on the weighted sum-rate … Show more
