论文摘要
这项工作在设置中考虑了毫米波通道的估计，在这种情况下，基础MMWAVE通道的参数会随着时间的流逝而动态变化，并且有一个单个漂移路径。在这种情况下，在估算块$ k+1 $的频道时，可以使用时间块$ k $的频道估计值作为附带信息（SI）。为了估计通道参数，我们采用了传递算法的Si-AID（复杂）近似消息，并将其性能与基于正交匹配的Pursuit的基准进行比较。
This work considers millimeter-wave channel estimation in a setting where parameters of the underlying mmWave channels are varying dynamically over time and there is a single drifting path. In this setting, channel estimates at time block $k$ can be used as side information (SI) when estimating the channel at block $k+1$. To estimate channel parameters, we employ an SI-aided (complex) approximate message passing algorithm and compare its performance to a benchmark based on orthogonal matching pursuit.
