A BPSK phase detection unit assumes that an input signal is a BPSK modulated signal in detecting a phase error of a recovered carrier and an 8PSK phase detection unit assumes that the input signal is an 8PSK modulated signal in detecting the phase error of the recovered carrier. An 8PSK frequency detection unit assumes that the input signal is an 8PSK modulated signal in detecting a frequency error of the recovered carrier. A selector selects the phase error detected by the BPSK phase detection unit or the phase error detected by the 8PSK phase detection unit. A carrier recovery unit recovers a carrier by adjusting a phase of the input signal, based on the selected phase error and the frequency error.
