On the achievable degrees of freedom of the MIMO X-channel with delayed CSIT
2016 IEEE Information Theory Workshop (ITW), 2016We consider the two-user multiple-input multiple-output X-channel where the transmitters 1, 2 have M 1 ,M 2 antennas and the receivers 1, 2 have N 1 ,N 2 antennas, respectively, and study the achievable number of degrees of freedom (DoF) of this network under the assumption of delayed channel state information at the transmitters.

On the degrees of freedom of SISO interference and X channels with delayed CSIT
2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011The SISO (single-input single-output) AWGN interference and X channels in i.i.d. fading environment are considered where the transmitters have the past channel state information (CSI) through noiseless feedback links. New transmission schemes are proposed for these channels that achieve degrees of freedom (DoF) values greater than one (except for two ...

The degrees of freedom region of the MIMO interference channel with delayed CSIT
2011 IEEE International Symposium on Information Theory Proceedings, 2011The degrees of freedom (DoF) region of the 2-user MIMO interference channel (IC) is studied under fast fading and the assumption of delayed channel state information at transmitters (CSIT) wherein the receivers know all channel matrices perfectly and the transmitters acquire this knowledge with a certain delay. An outer bound to the DoF region is first

Secure MIMO Interference Channel with Confidential Messages and Delayed CSIT
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019Secure degrees-of-freedom (SDoF) for multiple-input multiple-output (MIMO) interference channel with confidential messages and delayed channel state information at transmitter (CSIT) remains unclear, even for single-input single-output (SISO) case. In this paper, we propose an achievable SDoF for MIMO interference channel with confidential messages and

On degrees of freedom of layered two unicast networks with delayed CSIT
2012 IEEE International Symposium on Information Theory Proceedings, 2012In this paper we study the two unicast information flow problem over layered Gaussian networks with arbitrary number of nodes and connectivity, under the model of delayed channel state information (CSI) at transmitters and instantaneous CSI at receivers.

Finite Field X-Channels with Delayed CSIT and Common Messages
2018 IEEE International Symposium on Information Theory (ISIT), 2018We establish the capacity region of the two-user finite field X-Channels with delayed channel state information at the transmitters. We consider the most general case in which each transmitter has a common message for both receivers and a private message for each one of them. We derive a new set of outer-bounds for this problem that rely on an extremal
