Joint Annotator-and-Spectrum Allocation in Wireless Networks for Crowd Labelling
Xiaoyang Li, Guangxu Zhu, Kaiming Shen +3
The massive sensing data generated by Internet-of-Things will provide fuel for ubiquitous artificial intelligence (AI), automating the operations of our society ranging from transp…
Power Control for Massive MIMO Systems with Nonorthogonal Pilots
Xihan Chen, Kaiming Shen, Hei Victor Cheng +3
This letter shows that optimizing the transmit powers along with optimally designed nonorthogonal pilots can significantly reduce pilot contamination and improve the overall throug…
Mixed-Timescale Beamforming and Power Splitting for Massive MIMO Aided SWIPT IoT Network
Xihan Chen, Hei Victor Cheng, An Liu +2
Traditional simultaneous wireless information and power transfer (SWIPT) with power splitting assumes perfect channel state information (CSI), which is difficult to obtain especial…
Capacity Limits of Full-Duplex Cellular Network
Kaiming Shen, Reza K. Farsani, Wei Yu
This paper aims to characterize the capacity limits of a wireless cellular network with a full-duplex (FD) base-station (BS) and half-duplex user terminals, in which three independ…
Enhanced Channel Estimation in Massive MIMO via Coordinated Pilot Design
Kaiming Shen, Hei Victor Cheng, Xihan Chen +2
Pilot contamination is a limiting factor in multicell massive multiple-input multiple-output (MIMO) systems because it can severely impair channel estimation. Prior works have sugg…
