Achieving the DoF limits of the SISO X channel with imperfect-quality CSIT

Abstract

In the setting of the two-user single-input single-output X channel, recent works have explored the degrees-offreedom (DoF) limits in the presence of perfect channel state information at the transmitter (CSIT), as well as in the presence of perfect-quality delayed CSIT. Our work shows that the same DoF-optimal performance - previously associated to perfect… (More)
