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

Secure Degrees-of-Freedom of the MIMO X Channel With Delayed CSIT
IEEE Wireless Communications Letters, 2021 In this paper, we study the secure degrees-of-freedom (SDoF) characterization for the multiple-input multiple-output (MIMO) X channel with confidential messages and delayed CSIT. In particular, we propose a transmission scheme, which can be regarded as a generalization of the state-of-the-art scheme without security and with delayed CSIT.

2012 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.

MISO broadcast channel with delayed and evolving CSIT [PDF]
2013 IEEE International Symposium on Information Theory, 2013 The work considers the two-user MISO broadcast channel with gradual and delayed accumulation of channel state information at the transmitter (CSIT), and addresses the question of how much feedback is necessary, and when, in order to achieve a certain degrees-of-freedom (DoF) performance.

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 ...

Capacity Results for Binary Fading Interference Channels With Delayed CSIT [PDF]
IEEE Transactions on Information Theory, 2014 To study the effect of lack of up-to-date channel state information at the transmitters (CSIT), we consider two-user binary fading interference channels with Delayed-CSIT. We characterize the capacity region for such channels under homogeneous assumption where channel gains have identical and independent distributions across time and space, eliminating

An outer bound on the MIMO BC with evolving current CSIT and perfect delayed CSIT
2014 6th International Symposium on Communications, Control and Signal Processing (ISCCSP), 2014We derive a DoF outer bound for the two-user multiple-input multiple-output broadcast channel (MIMO BC) with good-quality delayed channel state information at the transmitter (perfect quality delayed CSIT), and with current CSIT of evolving quality (evolving current CSIT).

Scheduling Algorithms for MU-MIMO with Partial Current CSIT and Full Delayed CSIT
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013Recently, a novel class of high-performance multi-round MU- MIMO schemes were developed by Yang et al. [1] for the practically attractive scenario in which the transmitter has available partial channel state information (CSI) regarding the current state of the channel, but also full delayed CSI. We study methods for combining user scheduling with these

Transmitter cooperation in interference channel with delayed CSIT
2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014In this work we study the impact of limited transmitter cooperation on interference management in two-user interference channel. In particular, we consider the two-user interference channel with delayed channel state information at the transmitters (delayed CSIT).
