Hybrid Beamforming for Subarray-Level Movable Antenna Enhanced MU-MIMO Communications
Shanshan Zhang, Songjie Yang, Wenxuan Zhang +2
This study investigates subarray-level movable antenna (MA) architecture for multi-user MIMO (MU-MIMO) systems. Unlike conventional systems with fixed-position antennas (FPAs), the…
Extremely Large-Scale Dynamic Metasurface Antennas (XL-DMAs): Near-Field Modeling and Channel Estimation
Songjie Yang, Wanting Lyu, Boyu Ning +5
Dynamic metasurface antennas (DMAs) represent a novel transceiver array architecture for extremely large-scale (XL) communications, offering the advantages of reduced power consump…
Spectral and Energy Efficiency of Multicell Massive MIMO With Variable-Resolution ADCs Over Correlated Rayleigh Fading Channels
Youzhi Xiong, Sanshan Sun, Ning Wei +2
This paper analyzes the performance of multicell massive multiple-input and multiple-output (MIMO) systems with variable-resolution analog-to-digital converters (ADCs). In such an…
Throughput Optimal Listen-Before-Talk for Cellular in Unlicensed Spectrum
Ning Wei, Xingqin Lin, Wanwan Li +2
The effort to extend cellular technologies to unlicensed spectrum has been gaining high momentum. Listen-before-talk (LBT) is enforced in the regions such as European Union and Jap…
