App-Based 5G NR-TM and FRC Waveform Generation

This example shows how to use the 5G Waveform Generator app to generate NR test models (NR-TM) and NR uplink and downlink fixed reference channel (FRC) waveforms.

Open 5G Waveform Generator App

On the Apps tab of the MATLAB® toolstrip, under Signal Processing and Communications, click the 5G Waveform Generator app icon. This app opens the Wireless Waveform Generator app configured for 5G waveform generation.

Select 5G NR Waveform

In the Waveform Type section on the app toolstrip, click the waveform you want to generate. You can select any of these waveforms.

  • 5G Downlink FRC

  • 5G Uplink FRC

  • 5G Test Models

Generate 5G NR Waveform

In the left pane of the app, on the Waveform tab, you can set the parameters of the selected waveform. On the app toolstrip, in the Generation section, you can add impairments and set visualization tools. To visualize the waveform, click Generate. You can export the generated waveform to the MATLAB workspace as a structure in a .mat or .bb file.

For example, this picture shows the visualization results of a downlink FRC waveform using default parameters.

Transmit 5G NR Waveform

This feature requires Instrument Control Toolbox. To transmit the generated waveform, on the app toolstrip, click on the Transmitter tab and set up the instruments. You can use all the instruments supported by the rfsiggen (Instrument Control Toolbox) function.
