  • Method and device for notching the transmission band of an analog signal, in particular an MB-OFDM signal
    Patent number: 7720163
    Abstract: The transmission band of an analog signal to be transmitted is notched, including sub-carriers to be modulated from digital modulation coefficients respectively associated with the sub-carriers. The method includes providing an initial digital signal from successive frequency-domain groups each containing the digital modulation coefficients respectively associated to the sub-carriers. The initial signal is filtered with a frequency resolution greater than the frequency resolution of the frequency-domain groups to remove frequencies corresponding to the sub-carriers to be removed. The filtered signal is windowed using a windowing mask having a representation in the frequency-domain including a main lobe and secondary lobes. The power spectrum of the lobes decrease faster than the inverse of the frequency squared.
