Cross-Field Channel Parameter Estimation and Channel Characterization at THz Bands in Indoor Scenarios
Hengtai Chang, Cheng-Xiang Wang, Cunhua Pan +4
The paper presents indoor terahertz (260‑380 GHz) channel measurements with a virtual uniform linear array and introduces a cross‑field SAGE algorithm that jointly estimates near‑f…

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…
