App-Based LTE Waveform Generation

This example shows how to generate LTE test model (E-TM) and reference measurement channel (RMC) waveforms by using the LTE Waveform Generator app.

Open LTE Waveform Generator App

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

Select LTE Waveform

Choose the waveform you want to generate by selecting one of the options under LTE (4G) in the Waveform Type section of the app toolstrip. The app supports these waveforms.

  • Downlink RMC

  • Uplink RMC

  • Test Models (E-TM)

Generate LTE Waveform

Set the parameters for the selected waveform by specifying options in the Waveform tab on the left pane of the app. Add impairments and select visualization tools by specifying options in the Generation section of the app toolstrip. To visualize the waveform, click Generate. You can export the waveform to:

  • A MATLAB script with a .m extension

  • A file with a .bb or .mat extension

  • Your MATLAB workspace as a structure

For example, this figure shows the visualization results of a downlink RMC waveform with default parameters.

Transmit LTE Waveform

This feature requires Instrument Control Toolbox™ software. To transmit a generated waveform, click the Transmitter tab on the app toolstrip and configure the instruments. You can use any instrument supported by the rfsiggen (Instrument Control Toolbox) function.
