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…
Deep Learning for 1-Bit Compressed Sensing-based Superimposed CSI Feedback
Chaojin Qing, Qing Ye, Bin Cai +2
In frequency-division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems, 1-bit compressed sensing (CS)-based superimposed channel state information (CSI) feedba…
Fusion Learning for 1-Bit CS-based Superimposed CSI Feedback with Bi-Directional Channel Reciprocity
Chaojin Qing, Qing Ye, Wenhui Liu +1
Due to the discarding of downlink channel state information (CSI) amplitude and the employing of iteration reconstruction algorithms, 1-bit compressed sensing (CS)-based superimpos…
Label Design-based ELM Network for Timing Synchronization in OFDM Systems with Nonlinear Distortion
Chaojin Qing, Shuhai Tang, Chuangui Rao +3
Due to the nonlinear distortion in Orthogonal frequency division multiplexing (OFDM) systems, the timing synchronization (TS) performance is inevitably degraded at the receiver. To…
