Stochastic Hybrid Combining Design for Quantized Massive MIMO Systems

no code implementations24 Aug 2020 Yalin Wang, Xihan Chen, Yunlong Cai, Lajos Hanzo

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 (LADCs) at the receivers.

Joint Channel Assignment and Power Allocation for Multi-UAV Communication

no code implementations19 Aug 2020 Lingyun Zhou, Xihan Chen, Mingyi Hong, Shi Jin, Qingjiang Shi

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 favorable line-of-sight (LoS) propagation.

Hybrid Beamforming for Massive MIMO Over-the-Air Computation

no code implementations8 Jun 2020 Xiongfei Zhai, Xihan Chen, Jie Xu, Derrick Wing Kwan Ng

It is shown that for the special case with a fully-digital receiver at the AP, the achieved MSE of the massive MIMO AirComp system is inversely proportional to the number of receive antennas.

Energy Efficiency Optimization for Millimeter Wave System with Resolution-Adaptive ADCs

no code implementations18 May 2020 Hualian Sheng, Xihan Chen, Xiongfei Zhai, An Liu, Min-Jian Zhao

This letter investigates the uplink of a multi-user millimeter wave (mmWave) system, where the base station (BS) is equipped with a massive multiple-input multiple-output (MIMO) array and resolution-adaptive analog-to-digital converters (RADCs).
