Hierarchical Multi-Grid OMP for Ultra-Resolution Channel Estimation in THz UM-MIMO Systems
In this paper, we propose an ultra-resolution channel estimation scheme for ultra massive multiple input multiple output (UM-MIMO) systems operating in the Terahertz (THz) band. Specifically, we formulate the channel estimation as a non-convex sparse signal recovery problem, characterized by the abs...
