I need help with demodulating DSB-SC signals. I took the appproach of using the FFT as follows: I have a signal. I FFT it. Then i take real and imaginary part of the FFT and translate some values:
real[i] = real[i + xx] imag[i] = imag[i + xx]
then i reconstruct the signal by IFFT. The result is that a demodulation in the signal, very precise in frequency. But the problem is that there are some glitches due to spectral leakage.
According to your experience, is this a good approach for demodulating DSB-SC or is there a better approach?
Thanks a lot in advance
