Propagation Channel Models
Use 5G Toolbox™ System objects to model multi-input multi-output (MIMO) channels such as fading channels with different delay profiles and high-speed train (HST) propagation channels. You can also model the path loss and shadow fading between the base station (BS) and the user equipment (UE).
