This letter rethinks traditional precoding in multi-user wireless communications with movable
antennas (MAs). Utilizing MAs for optimal antenna positioning, we introduce a sparse …

Flexible antenna arrays (FAAs), distinguished by their rotatable, bendable, and foldable
properties, are extensively employed in flexible radio systems to achieve customized …

Three-dimensional (3D) spot beamfocusing (SBF), in contrast to conventional angular-
domain beamforming, concentrates radiating power within a very small volume in both radial …

This paper analyzes aerial Radio Access Networks for enhanced mobility coverage due to
superior Line of Site (LOS) access, which is vital for 5G and future 6G-connected at …

As wireless communication advances toward the 6G era, the demand for ultra-reliable, high-
speed, and ubiquitous connectivity is driving the exploration of new degrees-of-freedom …

Dynamic metasurface antennas (DMAs) represent a novel transceiver array architecture for
extremely large-scale (XL) communications, offering the advantages of reduced power …

Millimeter‐wave techniques have been developed significantly due to their benefits of
higher data rate compared with the lower band and more extensive coverage compared to …

Ultra-wideband MIMO radar can provide precise range and azimuth information of multiple
targets and is widely applied in military, aviation, transportation, and other fields. However …
