I have generated a 20 Mhz signal through 5G downlink FRC app in Matlab 2021a (attached a screenshot for specifications). How do we demodulate this signal?![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/882390/image.png)

Hey, Ashish,
I see that you are looking to demodulate a signal created with the 5G Downlink FRC in the Wireless Waveform Generator app.
To achieve this, utilize the app's Export feature located on the toolstrip to transfer the waveform as a structured data type into the MATLAB workspace or save it as a MAT-file (.mat). Furthermore, you can export the waveform configuration parameters by selecting 'Export to MATLAB Script' from the Export menu.
Once you have exported both the waveform and its configuration parameters, you can use the functions “nrOFDMDemodulate” and “nrPDSCHDecode” to demodulate and decode the PDSCH symbols.
You can refer to the following documentations to learn more about:
2. Function “nrOFDMDemodulate”:
3. Function “nrPDSCHDecode”:
I hope this helps!
