Abstract
A transmitter which is capable of producing an SSB signal having a sharp spectrum cut. The transmitter generates the SSB signal using an FFT circuit (103) which Fourier-transforms a transmission symbol, a zero insertion circuit (104) which zeros the component of either the USB component signal or the LSB component signal outputted from the FFT circuit (103), an IFFT circuit (105) which inverse-Fourier-transforms the output from the zero insertion circuit (104), and a parallel-serial conversion circuit (106) which parallel-serial-converts the output from the IFFT circuit (105).
