Enhanced Tracking and Beamforming Codebook Design for Wideband Terahertz Massive MIMO System
Xu Shi, Jintao Wang, Jian Song
True-time-delay (TTD) lines are recently applied inside Terahertz (THz) hybrid-precoding transceiver to acquire high beamforming gain against beam squint effect. However, beam trac…

Spatial-chirp Codebook-based Hierarchical Beam Training for Extremely Large-Scale Massive MIMO
Xu Shi, Jintao Wang, Zhi Sun +1
Extremely large-scale multiple-input multiple-output (XL-MIMO) promises to provide ultrahigh data rates in millimeter-wave (mmWave) and Terahertz (THz) spectrum. However, the spher…
