Modeling and Performance Analysis for Movable Antenna Enabled Wireless Communications [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2022
In this paper, we propose a novel antenna architecture called movable antenna (MA) to improve the performance of wireless communication systems. Different from conventional fixed-position antennas (FPAs) that undergo random wireless channel variation ...

Movable-Antenna Array Enhanced Beamforming: Achieving Full Array Gain With Null Steering [PDF]

open access: yesIEEE Communications Letters, 2023
Conventional beamforming with fixed-position antenna (FPA) arrays has a fundamental trade-off between maximizing the signal power (array gain) over a desired direction and simultaneously minimizing the interference power over undesired directions.
