Title: METHOD FOR PROCESSING SENT DATA, AND TRANSMITTER
Abstract:
Disclosed in the present invention are a method for processing sent data, and a transmitter. The method comprises: obtaining a modulation signal in each of M subbands according to sent data of the M subbands in a working frequency band of a transmittter, M being a positive integer greater than 1; separately performing first IDFT on the modulation signal of each subband among the M subbands; performing second IDFT on a signal, on which the first IDFT has been performed, of the M subbands; weighting, according to a filter coefficient sequence, a sequence obtained by performing the second IDFT; and performing shifting accumulation on the weighted sequence, so as to obtain a sent signal. The method for processing sent data and the transmitter in embodiments of the present invention can decrease the complexity of filtering.
