<p>Multiple carrier transmission systems such as used for Digital Audio Broadcasting (DAB) typically require significant complexity in the implementation of the receiver. This is usually done using an FFT (fast fourier transformation) on the input data (or baseband representation). A method is proposed of simplifying the demodulation, in the case where only some of the carriers are required and these are regularly spaced in frequency. This can be applied to mobile radio equipment.</p> |
