There is no known network with instantaneous channel state information at the transmitters (CSIT) for which (output) feedback enhances the degrees of freedom (or the signaling dimensions) of the network. In this paper, we show that the DoF of wireless networks with delayed CSIT however, can increase with output feedback. This result is shown by obtaining the degrees of freedom (DoF) region for the multiple-input multiple-output (MIMO) fast fading interference channel (IC) with an arbitrary… CONTINUE READING
