摘要： Provided is a receiver including a receiving unit, a demodulator-decoder unit, a synchronization detecting unit, and an output control unit. The receiving unit receives digital broadcasting. The demodulator-decoder unit obtains an output including a transport stream through a demodulating processing and a decoding processing performed on a reception signal received by the receiving unit. The synchronization detecting unit secures synchronization on the basis of the reception signal received by the receiving unit, and generates a timing signal to be used in the demodulating processing and in the decoding processing. The output control unit outputs the output including the transport stream from the demodulator-decoder unit if the synchronization is secured. The output control unit fixes a logic level of the output including the transport stream if the synchronization is not secured.

摘要： An OFDM synchronization demodulation circuit includes a receiving circuit for receiving an orthogonal frequency division multiplexing (OFDM) modulation signal. An orthogonal detection circuit orthogonally detects the OFDM modulation signal from the receiving circuit using a detected carrier. A demodulation circuit orthogonally demodulates the detected OFDM multiplex modulation signal from the orthogonal detection circuit by sampling the OFDM multiplex detection signal using a detected clock. A constellation analyzing circuit analyzes the constellation of demodulated symbols of predetermined carriers in the demodulated OFDM multiplex signal signal. A carrier frequency deviation detection circuit detects a frequency deviation of the detected carrier based on a rotation of the constellation of the demodulated symbol detected by the constellation analyzing circuit. A carrier detection circuit responsive to the frequency deviation detected by the carrier frequency deviation detection circuit controls the detected carrier. A clock frequency deviation detection circuit detects a frequency deviation of the detected clock based on rotations of the constellations of at least two demodulated symbols detected by the constellation analyzing circuit. A clock detection circuit controls the detected clock based on the frequency deviation detected by the clock frequency deviation detection circuit.
