Channel Estimation for Full-duplex Multi-tag Ambient Backscatter Communication Systems with I/Q Imbalance
Saeed Abdallah, Mahmoud A. Albreem, Bassel Al Homssi +2
Ambient backscatter communication (AmBC) has emerged as a highly attractive paradigm for energy-efficient communication. Full-duplex multi-tag AmBC systems provide the scalability…
EM-Based Channel Estimation for mMIMO LEO SATCOM Under Imperfect Doppler Compensation
Abdollah Masoud Darya, Saeed Abdallah
Massive multiple-input multiple-output low-Earth-orbit communication channels are highly time-varying due to severe Doppler shifts and propagation delays. While satellite-mobility-…
Novel Selection Schemes for Multi-RIS-Assisted Fluid Antenna Systems
Mahmoud Aldababsa, Taissir Y. Elganimi, Mahmoud A. Albreem +1
This paper investigates the performance of a multi-reconfigurable intelligent surface (RIS)-assisted fluid antenna system (FAS). In this system, a single-antenna transmitter commun…
Semi-blind Channel Estimation for Massive MIMO LEO Satellite Communications
Abdollah Masoud Darya, Saeed Abdallah
This letter proposes decision-directed semi-blind channel estimation for massive multiple-input multiple-output low-Earth-orbit satellite communications. Two semi-blind estimators…
