A Near Field Low Time Complexity Beam Training Scheme Based on Spatial Orthogonal Decomposition
Xiyuan Liu, Qingqing Wu, Rui Wang +1
With the application of high-frequency communication and extremely large MIMO (XL-MIMO), the near-field effect has become increasingly apparent. The near-field beam design now requ…

Hierarchical Codebook Design and Analytical Beamforming Solution for IRS Assisted Communication
Xiyuan Liu, Qingqing Wu, Die Hu +2
In intelligent reflecting surface (IRS) assisted communication, beam search is usually time-consuming as the multiple-input multiple-output (MIMO) of IRS is usually very large. Hie…
