Sensing and Backscatter Communication Integration: Realizing Efficiency in Wireless Systems for IoT
Shayan Zargari, Diluka Galappaththige, Chintha Tellambura
In an era driven by the Internet of Things (IoT) and rapid wireless communication advances, the synergy between sensing and backscatter communication (BackCom) has emerged as a fro…
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…
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…
