A digital broadcast receiver is provided which can reliably receive transmitter identification information. The carrier-dependent components of the DAB broadcast signal are derived by an FFT circuit 32. Carrier-power detectors 41 and 50 calculate a carrier-power value by using the carrier-components of a NULL symbol and PRS. A correction amount determining circuit 51 determines a correction amount. In accordance with the correction amount, a correction circuit 52 corrects a carrier-power value of each carrier. A TII decoder 42 judges a transmitted carrier in accordance with the corrected carrier-power value of each carrier, and decodes the transmitter identification information in accordance with the judged transmitted carriers. <IMAGE> |
