<p>A transmitter of a complex SSB signal in which the bit error rate characteristic on the receiving side is improved remarkably. The transmitter generates the SSB signal using an N-fold oversampler (102) which performs N-fold oversampling processing for each transmission symbol, a serial-parallel conversion circuit (104) which parallelizes the sampling data obtained by the N-fold oversampler (102) to parallel data of N systems for each symbol, an N-point FFT circuit (105) which fast-Fourier-transforms the parallel data of the N systems, a zero insertion circuit (106) which zeros the component of either the USB component signal or the LSB component signal outputted from the FFT circuit (105), an IFFT circuit (107) which inverse-fast-Fourier-transforms the output from the zero insertion circuit (106), and a parallel-serial conversion circuit (108) which parallel-serial-converts the output from the IFFT circuit (107).</p> |
