Hi everyone.
In the example ( FBMC vs. OFDM Modulation ), Periodogram function uses Hann window for FBMC modulation , while it uses Rectangular window (rectwin) for OFDM.
FBMC
[specFBMC, fFBMC] = periodogram(currSym, hann(KF, 'periodic'), KF*2, 1);
OFDM
[specOFDM,fOFDM] = periodogram(ifftOut, rectwin(length(ifftOut)), ...
numFFT*2, 1, 'centered');
Is there any explanation ?
