Abstract :
In this paper, we investigate the effect of feedback on two-user MIMO interference channels. At first, the capacity region of MIMO interference channels with feedback is characterized within a constant number of bits, where this constant is independent of the channel matrices. Further, the generalized degrees of freedom region for the MIMO interference channel with feedback is characterized.
