WIPO Patent Application WO/2015/178372

Kind Code:

A1

Abstract:

[Problem] To efficiently compensate for the influence of a Doppler shift. [Solution] A receiving device (101) is provided with: a Doppler estimator (11) which estimates the Doppler shift frequency (fdc) of a received signal; a multiplier (12) and an LPF (13) which detect the received signal on the basis of the carrier frequency (fc) of the received signal and the Doppler shift frequency (fdc) estimated by the Doppler estimator (11); a timing corrector (161) which corrects timing (T) at which the symbol of the received signal detected by the LPF (13) such that the timing can follow a Doppler shift; a symbol extractor (14) which extracts, from the signal detected by the LPF (13), a reception symbol at the timing corrected by the timing corrector (161); and an adaptive equalizer (15) which estimates and determines a symbol from the reception symbol extracted by the symbol extractor (14).
