Abstract:
1. A transmitter which processes a signal to be a transmission target, the transmitter comprising: baseband limiter means operable to apply a peak reduction process to digital signals to be transmitted by the transmitter on a plurality of carriers in a baseband; band limiting filter means operable to apply a band limitation process to the digital signal on each of the carriers output from the baseband limiter means to which the peak reduction process is applied by the baseband limiter means; quadrature modulation processing means operable to apply a quadrature modulation process to the digital signal on each of the carriers output from the band limiting filter means to which the band limiting process is applied by the band limiting the filter means; adding means operable to add the digital signal on each of the carriers output from the quadrature modulation processing means to which the quadrature modulation process is applied by the quadrature modulation processing means; and intermediate frequency limiter means operable to apply a peak reduction process to a signal that is a result of adding the digital signals by the adding means in an intermediate frequency band, wherein the intermediate frequency limiter means comprises:
