Abstract: A first switching circuit (21) outputs a first radio signal representing a plurality of time-division multiplexed programs and a second radio signal other than the first radio signal, one at a time according to a switching signal. A voltage control oscillator (27) outputs a local signal at a frequency suitable for whichever signal outputted.

Abstract: A synchronization error occurs when a DTV signal is distorted on a transmission path and this deteriorates demodulation capability. The digital demodulation device and the synchronization detecting method of the invention can correct the synchronization position when determining that a synchronization error has occurred. A controller receives a center tap coefficient, for example, from a waveform equalizer and compares the coefficient with a given center tap coefficient threshold. If the coefficient is smaller than the threshold, the controller determines that a synchronization detector has made a synchronization error and outputs a control signal. The synchronization detector receiving the control signal re-detects a sync signal included in a received signal, to detect a new correct sync signal and thus correct the synchronization error.

Abstract: An OFDM baseband signal that has undergone a synchronization carrier modulation or a differential carrier modulation is inputted to a complex signal converter for nonlinear distortion equalization so as to be converted according to the N-th order function conversion characteristics (N>1). Then, nonlinear distortion in the OFDM baseband signal is compensated for. At this time, the following is used as a conversion equation: y(n)=x(n)+?am(n)xm(n)(m>1) wherein the values of the input signal, the output signal and the coefficient for m-th order distortion equalization at time n are, respectively, x(n), y(n) and am(n).

Abstract: An input signal DT contains a segment synchronization signal compliant with the ATSC standard. A clock multiplication section 111 multiplies a clock CK. A switchable sampling section 112 selects a sample point from among a plurality of timing points that are defined by the multiplied clock, and samples the input signal DT at the selected sample point. Moreover, the switchable sampling section 112 switches sample points from one to another in a synchronization-unestablished state. Once the segment synchronization is established, a synchronization detection device may maintain a synchronization-established state until the field synchronization detection fails, or the synchronization detection device may output a synchronization detection signal after shifting it in the time direction based on a bit error rate RT of the input signal.

Abstract: A tuner has a dual AGC function, and frequency-converts an input signal into an IF signal. An orthogonal detector calculates a complex signal from the IF signal. A demodulator demodulates a digital signal from the complex signals. An error corrector corrects the error of the digital signal. A signal level detector calculates a level judgment signal from the IF signal. A demodulation level detector detects a signal level of a demodulation signal on a desired band from an output signal of the demodulator. When a demodulation level judgment unit generates a judgment signal representing an influence from interference waves in adjacent channel affecting on a signal on the desired band from the demodulation signal, a control signal generator feeds back a gain control signal to the tuner in accordance with the judgment signal.

In the digital demodulation apparatus, a receive level variation detector detects receive level variation, an amount of noise components of the received digital signal wave. A gain controller 15 controls the gain with a receive level variation adaptive control signal based on the detected receive level variation, the amount of noise components.
