In order to, with respect to a signal modulated by a modulation method in which four kinds of SSB elements are orthogonally disposed around a common carrier frequency domain, suppress intersymbol interference in a time domain when the four kinds of SSB elements are separated at time of demodulation, in a representative embodiment, a first carrier wave tuned to a received signal, and a second carrier wave orthogonal to the first carrier wave are generated, a first signal synchronized with a symbol signal of the received signal, and a second signal obtained by Hilbert transforming the first signal are generated, a first local signal obtained by modulating the first signal by the first carrier wave, a second local signal obtained by modulating the first signal by the second carrier wave, a third local signal obtained by modulating the second signal by the first carrier wave, and a fourth local signal obtained by modulating the second signal by the second carrier wave are generated, and the received signal is demodulated by being detected by the first to fourth local signals. |
