RNet: 2D Deep Residual Learning with Height Embedding for 3D Radio Map Estimation
Huiting Rao, Junyuan Wang, Huiling Zhu +1
Acquiring channel knowledge is required by many applications. For instance, handover in cellular networks is mainly decided based on the knowledge of pathloss. In contrast to tradi…
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 Novel Non-Stationary Channel Emulator for 6G MIMO Wireless Channels
Yuan Zong, Lijian Xin, Jie Huang +1
The performance evaluation of sixth generation (6G) communication systems is anticipated to be a controlled and repeatable process in the lab, which brings up the demand for wirele…
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…
Ray-Tracing Channel Modeling for LEO Satellite-to-Ground Communication Systems
Jiahao Ning, Jinhao Deng, Yuanfang Li +6
Based on the vision of global coverage for sixth-generation (6G) wireless communication systems, the low earth orbit (LEO) satellite-to-ground channel model for urban scenarios has…
