Continuous Fluid Antenna Sampling for Channel Estimation in Cell-Free Massive MIMO
Masoud Kaveh, Farshad Rostami Ghadi, Francisco Hernando-Gallego +3
In this letter, we develop a continuous fluid antenna (FA) framework for uplink channel estimation in cell-free massive multiple-input and multiple-output (CF-mMIMO) systems. By mo…
Fluid Antenna-Enabled Backscatter Communication under Imperfect Channel Observations
Masoud Kaveh, Farshad Rostami Ghadi, Riku Jantti +2
Ambient backscatter communication (AmBC) enables ultra-low-power connectivity by allowing passive backscatter devices (BDs) to convey information through reflection of ambient sign…
