On Secure Uplink Transmission in Hybrid RF-FSO Cooperative Satellite-Aerial-Terrestrial Networks
Yuanyuan Ma, Tiejun Lv, Gaofeng Pan +2
This work investigates the secrecy outage performance of the uplink transmission of a radio-frequency (RF)-free-space optical (FSO) hybrid cooperative satellite-aerial-terrestrial…
Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model
Ang Chen, Li Chen, Yunfei Chen +3
The adoption of large-scale antenna arrays at high-frequency bands is widely envisioned in the beyond 5G wireless networks. This leads to the near-field regime where the wavefront…
Effect of Strong Time-Varying Transmission Distance on LEO Satellite-Terrestrial Deliveries
Yuanyuan Ma, Tiejun Lv, Tingting Li +3
In this paper, we investigate the effect of the strong time-varying transmission distance on the performance of the low-earth orbit (LEO) satellite-terrestrial transmission (STT) s…
Joint Communication and Sensing: Models and Potential of Using MIMO
Xinran Fang, Wei Feng, Yunfei Chen +2
The sixth-generation (6G) network is envisioned to integrate communication and sensing functions, so as to improve the spectrum efficiency (SE) and support explosive novel applicat…
Hierarchical-Absolute Reciprocity Calibration for Millimeter-wave Hybrid Beamforming Systems
Li Chen, Rongjiang Nie, Yunfei Chen +1
In time-division duplexing (TDD) millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems, the reciprocity mismatch severely degrades the performance of the h…
