thank you for this bug report. To run the waveform comparison we can offer a quick fix. Please download https://owncloud.nt.tuwien.ac.at/index.php/s/bK0tlBLw1rfRkmS with the password 5G_sim. It contains the file UFMC2.m, which belongs in the +Modulation folder as well as a folder “Theory” that belongs in the main directory of the simulator. With this you should be able to run the waveform comparison again. you probably have to change UFMC back to UFMC2 in line 142 of Comparision_5GWaveforms.m.
Please let us know, if you encounter any further problems.
