Description

The Wireless Channel Designer app enables you to design and analyze wireless channels. When you configure the app for 5G Toolbox™, you can design and analyze 5G NR channels.

Using the app configured for 5G Toolbox, you can:

  • Configure 5G tapped delay line (TDL) channel parameters. Each TDL channel model parameter in the app corresponds to a property of the nrTDLChannel System object™.

  • Visualize the power delay profile, impulse response, and OFDM response of the configured channel.

  • Export a TDL channel configuration and the path gains to workspace variables or a .mat file.

  • Export a TDLchannel configuration to an executable MATLAB® script. Use the script to programmatically generate the path gains and pass a waveform through the channel.

To design and analyse channels other than 5G NR channels, you must reconfigure the app. For a full list of features, see Wireless Channel Designer in the Communications Toolbox™ documentation.

Wireless Channel Designer app configured for 5G TDL channel design and analysis

Open the Wireless Channel Designer App

MATLAB Toolstrip: On the Apps tab, under Signal Processing and Communications, click the Wireless Channel Designer app icon: Image of wireless channel designer icon.

MATLAB Command Prompt: Enter wirelessChannelDesigner.

To configure the app for 5G Toolbox, in the Channel Type section on the app toolstrip, click the 5G TDL channel type icon: 5G TDL icon.

Examples

This example shows how to use the Wireless Channel Designer app to design and analyze a 5G NR channel model and how to export the channel configuration (requires 5G Toolbox™).

Open Wireless Channel Designer App

On the Apps tab of the MATLAB® toolstrip, under Signal Processing and Communications, click the Wireless Channel Designer app icon.

Select 5G Channel Type

In the Channel Type section on the app toolstrip, click the 5G TDL channel type icon to configure the app for 5G Toolbox™.

Design and Analyze 5G TDL Channel

Design a 5G TDL channel by using the parameters in the app. Each parameter corresponds to a property of the nrTDLChannel System object™. On the app toolstrip, in the Analysis section, you can select visualization scopes and set the analysis parameters. When you click Analyze, the app displays the analysis results using the selected scopes.

For example, this figure shows the power delay profile, impulse response, and OFDM response scopes of the 5G TDL channel with default parameters.

Export 5G TDL Channel and Path Gains to MATLAB Workspace or File

To export the 5G TDL channel configuration and path gains, on the app toolstrip, in the Export section, select Export to Workspace or Export to File. The app exports the channel configuration as an nrTDLChannel object and the path gains as a complex matrix in the MATLAB workspace or a MAT file (.mat).

Export 5G TDL Channel to MATLAB Script

To export the 5G TDL channel configuration as a MATLAB script, on the app toolstrip, in the Export section, select Export MATLAB Script. You can use the script to programmatically generate the path gains and to pass a waveform through the channel.
