Abstract
An OFDM transmitter (100) is disclosed. The OFDM transmitter comprises: a sorter (103-1) for sorting plural input complex signals and partitioning them into plural groups; plural IFFTs (103-2) for performing inverse Fourier transform on the input complex signals in groups; a peak reducer (103-4) for performing peak reduction, based on outputs from at least one of the IFFTs; and a multiple discrete signal generator (103-5) for generating a designated number of discrete signals from outputs of the peak reducer.
