Amplitude Prediction from Uplink to Downlink CSI against Receiver Distortion in FDD Systems
Chaojin Qing, Zilong Wang, Qing Ye +2
In frequency division duplex (FDD) massive multiple-input multiple-output (mMIMO) systems, the reciprocity mismatch caused by receiver distortion seriously degrades the amplitude p…

LoS sensing-based superimposed CSI feedback for UAV-Assisted mmWave systems
Chaojin Qing, Qing Ye, Wenhui Liu +3
In unmanned aerial vehicle (UAV)-assisted millimeter wave (mmWave) systems, channel state information (CSI) feedback is critical for the selection of modulation schemes, resource m…
