How do you generate the most original clean data? #1

Your method is excelllent to generating the simulation data. And the experiment is worth learning. But I don't know how the original data is generated. I don't know why power leakage can be calculated using the 64 frequency points before and after.

I hope you can answer my questions. This is very important to us. image

Hi, Thanks for your question. The clean signal PSDs saved in file [clean_PSD_6mod_Mat.pth] was generated using Matlab. Functions/tools like pskmod(), comm.RaisedCosineTransmitFilter() can be used to generate the signal PSD. About the 64, I use sampling freq which is 3 times of the carrier freq to generate the PSD with length 64x3. I used the middle 64 as the mainlobe, and the other two 64-pts segments on the left and right as sidelobe, which is leaked to adjacent bands.
