RECEIVING DEVICE, DOPPLER FREQUENCY COMPUTATION METHOD, AND COMPUTER PROGRAM

摘要

An objective of the present invention is to properly compute a Doppler frequency even if there is a possibility that a phase of a channel estimate value is non-contiguous in the time direction. [Solution] A receiving device comprises: a receiving means (RF unit (11)) for receiving a transmitted signal which is transmitted from a transmission device; a transform means (FFT unit (12)) for transforming the transmitted signal which is received by the receiving means to a frequency region signal; an estimation means (channel estimation unit (13)) for executing a channel estimation process on the basis of the frequency region signal which is obtained by the transform means; and a computation means (Doppler frequency measurement unit (16)) for computing a Doppler frequency on the basis of a channel estimate value which is estimated by the estimation means. If there is a possibility that the phase of the channel estimation value may be non-contiguous in the time direction, the computation means carries out a correction process on data during the calculation which derives the Doppler frequency, and thereafter, computes the Doppler frequency.
