I have an OFDM signal, but the frequency interval is different. In this way, I want to use IFFT on uniform frequency data to get the time data. However, I do not know the exact time for the result of the IFFT signal. Do you know how I can do that?
N = 80
delta_f = 312.5e3
Frequency = np.arange(N) * delta_f
Frequency[40] = Frequency[39] + 2*delta_f # nonuniform frequency interval
Frequency_signal = np.random.rand(1000)
how to use nfft_adjoint(x, Frequency_signal)? what should I define as 'x'? Is there any place for me to input the nonuniform frequency interval?
