Deep Reinforcement Learning for Backscatter Communications: Augmenting Intelligence in Future Internet of Things

no code implementations21 Sep 2023 Wali Ullah Khan, Eva Lagunas, Zain Ali, Asad Mahmood, Chandan Kumar Sheemar, Manzoor Ahmed, Symeon Chatzinotas, Björn Ottersten

Backscatter communication (BC) technology offers sustainable solutions for next-generation Internet-of-Things (IoT) networks, where devices can transmit data by reflecting and adjusting incident radio frequency signals.

Signal Processing Based Antenna Pattern Characterization for MIMO Systems

no code implementations18 Aug 2023 Chandan Kumar Sheemar, Jorge Querol, Symeon Chatzinotas

Furthermore, it grants a much wider research community the ability to independently perform APC for emerging complex 6G antenna systems, without relying on anechoic chambers.

IRS Assisted MIMO Full Duplex: Rate Analysis and Beamforming Under Imperfect CSI

no code implementations16 Aug 2023 Chandan Kumar Sheemar, Sourabh Solanki, Jorge Querol, Sumit Kumar, Symeon Chatzinotas

In this manuscript, we present a novel approach to jointly optimize active and passive beamforming in a multiple-input-multiple-output (MIMO) FD system assisted by an IRS for weighted sum rate (WSR) maximization.

Robust Beamforming for IRS Aided MIMO Full Duplex Systems

no code implementations15 Aug 2023 Chandan Kumar Sheemar, Jorge Querol, Sourabh Solanki, Sumit Kumar, Symeon Chatzinotas

We also analyze the achievable WSR of an IRS-assisted FD with imperfect CSI, for which the lower and the upper bounds are derived.

Game-Theoretic Mode Scheduling for Dynamic TDD in 5G Systems

no code implementations26 Apr 2021 Chandan Kumar Sheemar, Leonardo Badia, Stefano Tomasin

We propose a low-complexity and decentralized solution, where power allocation and scheduling are decoupled.
