Abstract
In order to efficiently compensate for effects of the Doppler shift, a receiving device includes a Doppler estimator that estimates a Doppler-shift frequency fdc of a received signal. A multiplier and an LPF detect the received signal based on a carrier frequency fc of the received signal and the Doppler-shift frequency fdc estimated by the Doppler estimator. A timing corrector corrects a timing T for extracting symbols of the received signal after detection by the LPF so as to track the Doppler shift. A symbol extractor extracts received symbols from the received signal after detection by the LPF at a timing corrected by the timing corrector. An adaptive equalizer estimates and determines symbols from the received symbols extracted by the symbol extractor.
