Near-Field Directional Modulation for RIS-Aided Movable Antenna MIMO Systems with Hardware Impairments
Maolin Li, Feng Shu, Riqing Chen +2
Movable antennas (MAs) are a promising technology to achieve a significant enhancement in rate for future wireless networks. The pioneering investigation on near-field directional…
Revealing the evanescent components in Kronecker-product based codebooks: insights and implications
Jun Yang, Yijian Chen, Yunqi Sun +4
The orthogonal bases of discrete Fourier transform (DFT) has been recognized as the standard spatial-domain bases for Type I, Type II and enhanced Type II codewords by the 3rd Gene…
Patterned Beam Training: A Novel Low-Complexity and Low-Overhead Scheme for ELAA
Hongkang Yu, Yuan Si, Shujuan Zhang +1
Extremely large antenna arrays (ELAAs) can provide higher spectral efficiency. However, the use of narrower beams for data transmission significantly increases the overhead associa…
Fast Beam Training and Performance Analysis for Extremely Large Aperture Array
Yuan Si, Hongkang Yu, Yijian Chen
Extremely large aperture array (ELAA) can significantly enhance beamforming gain and spectral efficiency. Unfortunately, the use of narrower beams for data transmission results in…
