Signal data file of 40 MHz BW and 15KHz SCS of no noise is giving SSS constellation as if noise is present

Signal data file of 40 MHz BW and 15KHz SCS of no noise is giving SSS constellation as if noise is present. I have updated that nrB = 216 instead of 240 for this case and fft 4096 instead of 2048 for fft. I am getting the correct cell ID but still noise is being present in the values. Can you tell me why?

@catkira Please note that the above signal is generated using matlab

can u provide the file?

Here you go this is the matlab generated signal

@catkira Did you get any findings as I tried with a 20Mhz and 15scs signal generated from Matlab and same issue was difference was seen

Hi @catkira , Can you let me know?

[catkira]

I recommend that You compare the demodulation with Matlab and find where differences appear.
