Hi all
1. some one can tell what this lines means about the scaling ?
2. why is this needed , why not just use x_Time=ifft(X_Freq);
3. i noticed that norm^2 of x_Time is equal to 64 as the size of the FFT.
thx in advance
Code:
N=64; %FFT size or total number of subcarriers (used + unused) 64
Nst = Nsd + Nsp; %Number of total used subcarriers
x_Time=N/sqrt(Nst)*ifft(X_Freq);1. some one can tell what this lines means about the scaling ?
