Create, impair, visualize, and export LTE waveforms
The LTE Waveform Generator app enables you to create, impair, visualize, and export LTE waveforms.
The app provides these capabilities by using the Wireless Waveform Generator app configured for LTE waveform generation. Using the app, you can:
Generate LTE test model (E-TM) waveforms, as defined in section 6 of TS 36.141 [1].
Generate LTE downlink reference measurement channel (RMC) waveforms for user equipment (UE) performance testing, as defined in Annex A.3 of TS 36.101 [2].
Generate LTE uplink RMC waveforms for base station (BS) performance testing, as defined in Annex A of TS 36.104 [3].
Distort the LTE waveform by adding RF impairments, such as AWGN, phase offset, frequency offset, DC offset, IQ imbalance, and memoryless cubic nonlinearity.
Visualize the LTE waveform in constellation diagram, spectrum analyzer, OFDM grid, 3D spectrogram, and time scope plots.
Export
the LTE waveform to your workspace as a structure, to a
.mat
or a .bb
file, or to a runnable
MATLAB® script.
Note
You can use the MATLAB script to reproduce your waveform outside of the app.
Generate an LTE waveform that you can transmit using a connected lab
test instrument. The app can transmit a waveform by using instruments supported
by the rfsiggen
(Instrument Control Toolbox) function. Use of the transmit feature in the app
requires Instrument Control Toolbox™ software. For more information, see the documentation for Instrument Control Toolbox.
To create, impair, visualize, and export waveforms other than waveforms, you must reconfigure the app. For a full list of features, see the Wireless Waveform Generator app.
For more information, see Using Wireless Waveform Generator App.
MATLAB Toolstrip: On the Apps tab, under Signal
Processing and Communications, click the app icon.
MATLAB Command Prompt: Enter wirelessWaveformGenerator
. This command opens
the Wireless Waveform Generator app. To
configure the app for LTE waveform generation, in the
Waveform Type section, select one of the options
under LTE (4G).
