Two-Stage Channel Estimation Approach for Cell-Free IoT With Massive Random Access
Xinhua Wang, Alexei Ashikhmin, Zhicheng Dong +1
We investigate the activity detection and channel estimation issues for cell-free Internet of Things (IoT) networks with massive random access. In each time slot, only partial devi…
Long-term scheduling and power control for wirelessly powered cell-free IoT
Xinhua Wang, Xiaodong Wang, Alexei Ashikhmin
We investigate the long-term scheduling and power control scheme for a wirelessly powered cell-free Internet of Things (IoT) network which consists of distributed access points (AP…
Wirelessly Powered Cell-free IoT: Analysis and Optimization
Xinhua Wang, Alexei Ashikhmin, Xiaodong Wang
In this paper, we propose a wirelessly powered Internet of Things (IoT) system based on the cell-free massive MIMO technology. In such a system, during the downlink phase, the sens…
Self-Interference Suppression for the Full-Duplex Wireless Communication with Large-Scale Antenna
Pengbo Xing, Ju Liu, Chao Zhai +2
In this letter, we proposed a shared-antenna full-duplex massive MIMO model for the multiuser MIMO system. This model exploits a single antenna array at the base station (BS) to tr…
