Hierarchical-Absolute Reciprocity Calibration for Millimeter-wave Hybrid Beamforming Systems
Li Chen, Rongjiang Nie, Yunfei Chen +1
In time-division duplexing (TDD) millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems, the reciprocity mismatch severely degrades the performance of the h…
