Frequency domain phase correction

WebHence, in the frequency domain the individual subchannels will have the form of sinc functions where the first sidelobe is only some 13 dB below the main lobe of the subcarrier. A practical oscillator has spectral components around the centre frequency. These components cause the loss of orthogonality of the OFDM carriers. In the frequency ...
