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…
