Cache-Aided Retrospective Interference Alignment in SISO X Wireless Networks

open access: yesIEEE Access, 2020
In this paper, one class of single-input single-output (SISO) X networks with cache at both transmitters and receivers is considered. Specifically, the X networks consist of two transmitters and K receivers.

An Overview of Physical Layer Security in Wireless Communication Systems With CSIT Uncertainty

open access: yesIEEE Access, 2016
The concept of physical layer security builds on the pivotal idea of turning the channel's imperfections, such as noise and fading, into a source of security.

On the Degrees-of-freedom of the 3-user MISO Broadcast Channel with Hybrid CSIT [PDF]

open access: yes, 2014
The 3-user multiple-input single-output (MISO) broadcast channel (BC) with hybrid channel state information at the transmitter (CSIT) is considered. In this framework, there is perfect and instantaneous CSIT from a subset of users and delayed CSIT from ...

Retrospective Interference Alignment for the MIMO Interference Broadcast Channel [PDF]

open access: yes, 2015
The degrees of freedom (DoF) of the multiple-input multiple-output (MIMO) Interference Broadcast Channel (IBC) with 2 cells and 2 users per cell are investigated when only delayed channel state information is available at the transmitter side (delayed ...

Secrecy Degrees of Freedom of MIMO Broadcast Channels With Delayed CSIT [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
The degrees of freedom (DoF) of the two-user Gaussian multiple-input and multiple-output (MIMO) broadcast channel with confidential message (BCC) is studied under the assumption that delayed channel state information (CSI) is available at the transmitter. We characterize the optimal secrecy DoF (SDoF) region and show that it can be achieved by a simple

Can imperfect delayed CSIT be as useful as perfect delayed CSIT? DoF analysis and constructions for the BC

open access: yes2012 50th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2012
In the setting of the two-user broadcast channel, where a two-antenna transmitter communicates information to two single-antenna receivers, recent work by Maddah-Ali and Tse has shown that perfect knowledge of delayed channel state information at the transmitter (perfect delayed CSIT) can be useful, even in the absence of any knowledge of current CSIT.
