N2 - In this paper we analyze the generalized degrees of freedom (GDOF) and the DMT performances of both the symmetric and asymmetric MIMO Gaussian interference fading channel with a fixed-power-split HK scheme for two transmit-receive pairs. Exact characterizations of both the GDOF and DMT performance measures are given. It is shown in the SIMO case that when the number of receive antennas is at least two, full region of GDOF can be achieved, as if the non-intending transmitter does not exist. The same conclusion is applied to the DMT measure as well. In particular, if the channel is symmetric, both receivers are able to achieve the single-user performance regime.
