I am having IQ data of 5G NR signals, its with SCS of 120 KHz, QPSK, No of RBs as 66, PBCH positions at 11, phase compensation on at 1 GHz. I want support to plot the constellation.
.mat files available in the following link
Please help me.

Hi Pavan,
If you have IQ data in .mat file, open MATLAB and then load the mat file, which will bring the data present in .mat file to MATLAB workspace.
Then, to view the constellation, look at Scatter Plots and Contellation Diagrams.
Hope this helps.

I am trying out with the FRC A3-31 ( Precoding enabled PUSCH), the equalized constellation plot doesnt seem correctly plot QPSK constellation ( also not sure if nrTransformDeprecode is applied on received waveform).
Can you confirm how the original constellation of data bits in QPSK can be obtained from the EVM tool?
