Signal Detection in Ambient Backscatter Systems: Fundamentals, Methods, and Trends
Shayan Zargari, Azar Hakimi, Fatemeh Rezaei +2
Internet-of-Things (IoT) is rapidly growing in wireless technology, aiming to connect vast numbers of devices to gather and distribute vital information. Despite individual devices…
Cell-Free Bistatic Backscatter Communication: Channel Estimation, Optimization, and Performance Analysis
Diluka Galappaththige, Fatemeh Rezaei, Chintha Tellambura +1
This study introduces and investigates the integration of a cell-free architecture with bistatic backscatter communication (BiBC), referred to as cell-free BiBC or distributed acce…
RIS-Assisted Energy Harvesting Gains for Bistatic Backscatter Networks: Performance Analysis and RIS Phase Optimization
Diluka Galappaththige, Fatemeh Rezaei, Chintha Tellambura +1
Inexpensive tags powered by energy harvesting (EH) can realize green (energy-efficient) Internet of Things (IoT) networks. However, tags are vulnerable to energy insecurities, resu…
Adversarial Score-Based Generative Models for MMSE-achieving AmBC Channel Estimation
Fatemeh Rezaei, S. Mojtaba Marvasti-Zadeh, Chintha Tellambura +1
This letter presents a pioneering method that employs deep learning within a probabilistic framework for the joint estimation of both direct and cascaded channels in an ambient bac…
Time-Spread Pilot-Based Channel Estimation for Backscatter Networks
Fatemeh Rezaei, Diluka Galappaththige, Chintha Tellambura +1
Current backscatter channel estimators employ an inefficient silent pilot transmission protocol, where tags alternate between silent and active states. To enhance performance, we p…
NOMA-Assisted Symbiotic Backscatter: Novel Beamforming Designs Under Imperfect SIC
Fatemeh Rezaei, Diluka Galappaththige, Chintha Tellambura +1
Optimal beamforming designs under imperfect successive interference cancellation (SIC) decoding for a symbiotic network of non-orthogonal multiple access (NOMA) primary users and a…
Rate Analysis of Cell-Free Massive MIMO-NOMA With Three Linear Precoders
Fatemeh Rezaei, Chintha Tellambura, Aliakbar Tadaion +1
Although the hybrid of cell-free (CF) massive multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) promises massive spectral efficiency gains, the type o…
