Propagation Channel Models

CDL, TDL, and HST channel models and path loss configuration

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).

Functions

`nrCDLChannel`	Model CDL MIMO channel
`nrTDLChannel`	Model TDL MIMO channel model
`nrHSTChannel`	Model HST MIMO channel (Since R2022b)
`nrPathLossConfig`	Path loss configuration parameters (Since R2021b)
`nrPathLoss`	Path loss and shadow fading between BS and UE (Since R2021b)
