Abstract:
In order to increase a compensation range for Doppler shift compensation, this digital signal processing circuit is provided with a Doppler shift compensation unit which, on the basis of a sample sequence signal which is oversampled at N (where N is an integer at least equal to 2) times a symbol rate and includes a central sample corresponding to the timing at a symbol center, and a transition sample corresponding to the timing of a symbol transition, finds a Doppler shift amount included in the sample sequence signal and performs Doppler shift compensation. The Doppler shift compensation unit includes a symbol determining unit which performs a symbol determination with respect to the central sample and a determination with respect to the transition sample. The Doppler shift compensation unit switches between these determinations for each corresponding sample and performs said determinations in order to obtain a phase difference and thereby detect the Doppler shift amount.

Claim (Index 3):
The digital signal processing circuit according to  claim 1 , further comprising an upsampling circuit,\n wherein the symbol decision circuit comprises: a symbol decision part configured to perform a symbol decision with respect to the center sample; a transition point sample decision part configured to performing a decision with respect to the transition sample; a partway point sample decision part configured to perform a decision with respect to a partway point sample sampled by the upsampling circuit; and a circuit switch configured to switch between circuits for each sample in such a way that the center sample included in the sampling sequence signal is inputted to the symbol decision part, that the transition sample is inputted to the transition point sample decision part, and that the partway point sample is inputted to the partway point sample decision part.
