Channel Parameter Estimation and Characteristic Analysis at THz Bands in Hybrid Near-Field/Far-Field Scenarios
Hengtai Chang, Cheng-Xiang Wang, Cunhua Pan +4
The terahertz (THz) band is a promising candidate for high-data-rate transmission in future wireless communication systems, where large-scale antenna arrays are deployed to combat…
Beam Domain Channel Estimation for Spatial Non-Stationary Massive MIMO Systems
Lin Hou, Hengtai Chang, Cheng-Xiang Wang +2
In massive multiple-input multiple-output (MIMO) systems, the channel estimation scheme is subject to the spatial non-stationarity and inevitably power leakage in the beam domain.…
A Quasi-deterministic Channel Model for Underwater Acoustic Communication Systems
Yuxuan Yang, Yilin Ma, Hengtai Chang +1
In this paper, a quasi-deterministic (Q-D) model for non-stationary underwater acoustic (UWA) channels is proposed. This model combines the BELLHOP deterministic model and geometry…
Multi-Frequency Multi-Scenario Millimeter Wave MIMO Channel Measurements and Modeling for B5G Wireless Communication Systems
Jie Huang, Cheng-Xiang Wang, Hengtai Chang +2
Millimeter wave (mmWave) bands have been utilized for the fifth generation (5G) communication systems and will no doubt continue to be deployed for beyond 5G (B5G). However, the un…
