Title: Ofdm broadcast wave receiver
Inventor: YAMAUCHI KEIICHI
IPC: H04J11/00
Filed: 1995-02-20
Abstract: PURPOSE: To automatically discriminate whether received signals are of a wide band or a narrow band by subjecting broadcast waves to orthogonal frequency division multiplex into data signals, transmitting them as unit signals of different frame lengths corresponding to the band width of the broadcast waves and controlling a demodulation operation according to the result of discrimination of the frame length of the received signals. CONSTITUTION: The counted value of a counter 23 immediately before being reset by null detection signal indicates one frame length and the counted value is held in a holding circuit 24. The output signals of a comparator 25 for comparing the holding value of the circuit 24 with a prescribed value indicate whether the reception signals at present are the signals of the wide band or the signals of the narrow band. Thus, since the signals of the wide band are received when the holding value of the circuit 24 is larger than the prescribed value, the output signals of the comparator 25 are supplied to a control part as wide band detection signals. When the holding value of the circuit 24 is smaller than the prescribed value, they are supplied to the control part as narrow band detection signals.  Also, the prescribed value is set at a value capable of distinguishing the frame length in the case of the signals of the wide band from the frame length in the case of the signals of the narrow band.
