Capacity Results for Binary Fading Interference Channels with Delayed CSIT [PDF]

open access: yesIEEE 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

Full-Duplex Relay with Delayed CSI Elevates the SDoF of the MIMO X Channel [PDF]

open access: yesEntropy, 2021
In this article, the sum secure degrees-of-freedom (SDoF) of the multiple-input multiple-output (MIMO) X channel with confidential messages (XCCM) and arbitrary antenna configurations is studied, where there is no channel state information (CSI) at two ...

The DoF region of two‐user MIMO broadcast channel with delayed imperfect‐quality CSIT

open access: yesElectronics Letters, 2022
The channel state information at the transmitter (CSIT) play an important role in the performance of wireless networks. The CSIT model can be delayed and imperfect‐quality, since the feedback link has a delay and the channel state information (CSI ...

Block-Fading Channels with Delayed CSIT at Finite Blocklength [PDF]

open access: yes2014 IEEE International Symposium on Information Theory, 2014
In many wireless systems, the channel state information at the transmitter (CSIT) can not be learned until after a transmission has taken place and is thereby outdated.

MISO Broadcast Channel with Delayed and Evolving CSIT [PDF]

open access: yes2013 IEEE International Symposium on Information Theory, 2012
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 ...

MISO Broadcast Channel under Unequal Link Coherence Times and Channel State Information [PDF]

open access: yesEntropy, 2020
The broadcast channel may experience unequal link coherence times due to a number of factors including variation in node mobility or local scattering conditions.

Unified Space–Time-Message Interference Alignment: An End-to-End Learning Approach [PDF]

open access: yesEntropy
This paper investigates the performance of a multi-user multiple-input single-output (MU-MISO) broadcast channel under the practical constraints of imperfect, delayed, and quantized channel state information at the transmitter (CSIT).

Secure Retrospective Interference Alignment [PDF]

open access: yesEntropy, 2019
In this paper, the K-user interference channel with secrecy constraints is considered with delayed channel state information at transmitters (CSIT). We propose a novel secure retrospective interference alignment scheme in which the transmitters carefully

Two-User Erasure Interference Channels with Local Delayed CSIT [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
We study the capacity region of two-user erasure interference channels with local delayed channel state information at the transmitters. In our model, transmitters have local mismatched outdated knowledge of the channel gains.

Advancements in hybrid rice production: improvements in male sterility and synthetic apomixis for sustainable agriculture. [PDF]

open access: yesPlant Biotechnol J
Summary Rice serves as a staple food for approximately half of the world's population, and enhanced yields from hybrid rice play a crucial role in ensuring food security and augmenting incomes. However, the annual purchase and high cost of hybrid seeds hinder widespread hybrid rice adoption.
