How can I change FFT size without changing NRB in PUSCH ?

Hello everyone,

I am working on NR PUSCH Throughput. I am using MATLAB example for measuring Throughput, the default number of resource block (NRB) is 52 with FFT size 1024. but I want t ochange FFT size without changing NRB. would you please help me how can I do it.

I am looking forward to hear from you.

With Best Regards

Hi Alireza,

I haven't work dirrectly with NR PUSCH , But having a quick look on it I could suggest you do a modification of code in hofdmmodulate fuction.

You could set the desired ifft size manually with changing nFFT variable. I hope this is what you are looking for.
