Patent ID: 8488696

Claim:
A receiver device that receives a signal supplied to one or a plurality of ports as one or a plurality of received signals, comprising: one or a plurality of processors that comprises a timing detector that performs timing detection by detecting a signal position of a received signal allocated beforehand from among said one or plurality of received signals in order to form a signal waveform of said received signals allocated beforehand, a frequency offset compensating unit that compensates a frequency offset of the received signal that is timing-detected by said timing detector, a serial-to-parallel converter that subjects the received signal compensated by said frequency offset compensating unit to a serial-to-parallel conversion, a Fourier transform unit that performs a Fourier transform of the received signal subjected to the serial-to-parallel conversion by said serial-to-parallel converter, an equalizer that equalizes the received signal subjected to the Fourier transform by said Fourier transform unit to each frequency component, an inverse Fourier transform unit that subjects the received signal equalized by said equalizer to an inverse Fourier transform, and a parallel-to-serial converter that subjects the received signal subjected to the inverse Fourier transform by said inverse Fourier transform unit to a parallel-to-serial conversion; a signal synthesizer that synthesizes the signal waveform formed by said one or plurality of said processors; a demodulator that demodulates the signal waveform synthesized by said signal synthesizer; a phase offset estimating unit arranged on a received signal conversion path that runs from said timing detector to said demodulator to estimate a phase offset of the received signal on the basis of a unique word of each signal block contained in said received signal; and a phase offset compensating unit arranged on said received signal conversion path to compensate the phase offset of the received signal on said received signal conversion path on the basis of the phase offset estimated by said phase offset estimating unit.
