Linear Degrees of Freedom of the X-Channel with Delayed CSIT [PDF]
IEEE Transactions on Information Theory, 2014 We establish the degrees of freedom of the two-user X-channel with delayed channel knowledge at transmitters (i.e., delayed CSIT), assuming linear coding strategies at the transmitters.

Secure Degrees of Freedom of MIMO X-Channels with Output Feedback and Delayed CSIT [PDF]
IEEE Transactions on Information Forensics and Security, 2013 We investigate the problem of secure transmission over a two-user multi-input multi-output (MIMO) X-channel in which channel state information is provided with one-unit delay to both transmitters (CSIT), and each receiver feeds back its channel output to

Achievable DoF Regions of Three-User MIMO Broadcast Channel With Delayed CSIT [PDF]
IEEE Transactions on Communications, 2021 For the two-user multiple-input multiple-output (MIMO) broadcast channel with delayed channel state information at the transmitter (CSIT) and arbitrary antenna configurations, all the degrees-of-freedom (DoF) regions are obtained. However, for the three-user MIMO broadcast channel with delayed CSIT and arbitrary antenna configurations, the DoF region ...

Transmit Beamforming for MISO Broadcast Channels With Statistical and Delayed CSIT [PDF]
IEEE Transactions on Communications, 2015 This paper focuses on linear beamforming design and power allocation strategy for ergodic rate optimization in a two-user Multiple-Input-Single-Output (MISO) system with statistical and delayed channel state information at the transmitter (CSIT). We propose a transmission strategy, denoted as Statistical Alternative MAT (SAMAT), which exploits both ...

Optimal Use of Current and Outdated Channel State Information - Degrees of Freedom of the MISO BC with Mixed CSIT [PDF]
IEEE Communications Letters, 2012 We consider a multiple-input-single-output (MISO) broadcast channel with mixed channel state information at the transmitter (CSIT) that consists of imperfect current CSIT and perfect outdated CSIT. Recent work by Kobayashi et al. presented a scheme which

Degrees of Freedom of Time Correlated MISO Broadcast Channel with Delayed CSIT [PDF]
IEEE Transactions on Information Theory, 2012 We consider the time correlated multiple-input single-output (MISO) broadcast channel where the transmitter has imperfect knowledge on the current channel state, in addition to delayed channel state information. By representing the quality of the current

Degrees of Freedom of Multi-Hop MIMO Broadcast Networks with Delayed CSIT [PDF]
IEEE Wireless Communications Letters, 2013 We study the sum degrees of freedom (DoF) of a class of multi-layer relay-aided MIMO broadcast networks with delayed channel state information at transmitters (CSIT). In the assumed network a K-antenna source intends to communicate to K single-antenna destinations, with the help of N-2 layers of K full-duplex single-antenna relays.

The Degrees of Freedom Region of Temporally Correlated MIMO Networks With Delayed CSIT [PDF]
IEEE Transactions on Information Theory, 2014 We consider the temporally-correlated Multiple-Input Multiple-Output (MIMO) broadcast channels (BC) and interference channels (IC) where the transmitter(s) has/have (i) delayed channel state information (CSI) obtained from a latency-prone feedback channel as well as (ii) imperfect current CSIT, obtained, e.g., from prediction on the basis of these past
