Reduction of the peak to average power ration in multicarrier systems |
摘要 |
<p>The disclosure relates to digital radio broadcasting and television broadcasting systems. The digital signals provided by the modulator in quadrature at the frequency (F0) are applied to a processing circuit that carries out a conversion according to a determined relationship in order to reduce the peak factor (Fc) of the signals applied to the amplifier of the transmitter. The digital signals processed are applied to a band-pass filter centered on (f0) to attenuate the spectral components introduced by the processing operation. <IMAGE></p> |
