I learned from a paper that we can configure the amplitude of the signal by using the IFFT scaling value. If we change the scaling values to 1,2,2 for the 3 stages respectively, it will make the output signal strength equal to 1/4 of the non-scaled amplitude.
But I can't find where to set the three scaling values.
I learned from the sample code and book that ifft has 3 parameters, I tried to change the second parameter, but found that it reports an error.
tx_payload_mat = ifft(ifft_in_mat, N_SC, 1);

okay, Thanks for you reply.

I learned from the official website that ifft's syntax:
X = ifft(Y)
X = ifft(Y,n)
X = ifft(Y,n,dim)
X = ifft(___,symflag)
If I set n=64, it means 64 points ifft, but if I need to set the scaling value to (4,4,4) or (1,2,2), how should I do?
Thanks.
