Channel Correlation Matrix Extrapolation Based on Roughness Calibration of Scatterers
Heling Zhang, Xiujun Zhang, Xiaofeng Zhong +1
To estimate the channel correlation matrix (CCM) in areas where channel information cannot be collected in advance, this paper proposes a way to spatially extrapolate CCM based on…
