Joint User Scheduling and Resource Allocation for Millimeter Wave Systems Relying on Adaptive-Resolution ADCs
Xihan Chen, Yunlong Cai, An Liu +1
Millimeter wave (mmWave) communication systems using adaptive-resolution analog-to-digital converters (RADCs) have recently drawn considerable interests from the research community…
Joint Channel Assignment and Power Allocation for Multi-UAV Communication
Lingyun Zhou, Xihan Chen, Mingyi Hong +2
Unmanned aerial vehicle (UAV) swarm has emerged as a promising novel paradigm to achieve better coverage and higher capacity for future wireless network by exploiting the more favo…
Stochastic Hybrid Combining Design for Quantized Massive MIMO Systems
Yalin Wang, Xihan Chen, Yunlong Cai +1
Both the power-dissipation and cost of massive multiple-input multiple-output (mMIMO) systems may be substantially reduced by using low-resolution analog-to-digital converters (LAD…
Joint Beam Training and Data Transmission Design for Covert Millimeter-Wave Communication
Jiayu Zhang, Min Li, Shihao Yan +4
Covert communication prevents legitimate transmission from being detected by a warden while maintaining certain covert rate at the intended user. Prior works have considered the de…
Stochastic Transceiver Optimization in Multi-Tags Symbiotic Radio Systems
Xihan Chen, Hei Victor Cheng, Kaiming Shen +2
Symbiotic radio (SR) is emerging as a spectrum- and energy-efficient communication paradigm for future passive Internet-of-things (IoT), where some single-antenna backscatter devic…
Hybrid Beamforming for Massive MIMO Over-the-Air Computation
Xiongfei Zhai, Xihan Chen, Jie Xu +1
