摘要

为了在无法提前收集信道信息的地区估算信道相关矩阵(CCM),本文提出了一种基于传播场景中散射体表面粗糙度参数校准来推算信道相关矩阵的方法。我们根据某些特定区域的 CCM 数据校准了场景散射体的粗糙度参数。根据这些校准后的粗糙度参数,我们可以通过光线跟踪生成场景中任何其他区域的 CCM 预测值。仿真结果表明,本文提出的通道外推方法可以有效地实现不同区域之间的 CCM 频域外推,甚至从一个域到另一个域的外推。

Channel Correlation Matrix Extrapolation Based on Roughness Calibration of Scatterers
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 the calibration of the surface roughness parameters of scatterers in the propagation scene. We calibrate the roughness parameters of scene scatters based on CCM data in some specific areas. From these calibrated roughness parameters, we are able to generate a good prediction of the CCM for any other area in the scene by performing ray tracing. Simulation results show that the channel extrapolation method proposed in this paper can effectively realize the extrapolation of the CCM between different areas in frequency domain, or even from one domain to another.
