A Novel Dynamic Ray-Tracing Channel Model for 6G LEO Satellite-to-Ground Communication Systems
Songjiang Yang, Cheng-Xiang Wang, Yinghua Wang +4
The sixth generation (6G) communication systems envision a space-air-ground integrated network, making accurate satellite-to-ground (S2G) channel modeling crucial for communication…
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.…
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…
An Efficient Pre-Processing Method for 6G Dynamic Ray-Tracing Channel Modeling
Songjiang Yang, Cheng-Xiang Wang, Yinghua Wang +3
The ray-tracing is often employed in urban areas for channel modeling with high accuracy but encounters a substantial computational complexity for high mobility scenarios. In this…
