A digital audio broadcasting receiver includes: an analog-digital converter for converting a plurality of transfer frames from an analog signal format into a digital signal format based on a clock signal having a fixed frequency and for outputting the first transfer frame; a demodulator for demodula

A digital audio broadcasting receiver includes: an analog-digital converter for converting a plurality of transfer frames from an analog signal format into a digital signal format based on a clock signal having a fixed frequency and for outputting the first transfer frame; a demodulator for demodulating the first transfer frame from a first frame processing start position for the first transfer frame; an audio decoder for generating audio data containing a plurality of audio samples based on the data symbol contained in the first transfer frame which has been demodulated by the demodulator; a transfer path characteristics calculator for generating a transfer path characteristics signal representing transfer path characteristics based on the reference symbol contained in the first transfer frame which has been demodulated by the demodulator; and a frame processing start position control section for controlling a second frame processing start position for the second transfer frame, by outputting to the demodulator a position control signal representing a difference between a predetermined frame processing reference start position and the first frame processing start position for the first transfer frame based on the transfer path characteristics signal, so that the second frame processing start position for the second transfer frame coincides with the predetermined frame processing reference start position.
