Title: Ofdm receiver
Inventor: SUGITA YASUSHI
IPC: H04J11/00
Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To estimate the position of an adjacent analog interfering wave with high accuracy. SOLUTION: A frequency difference estimate unit 110 receives a segment number 111 definitely decided by a sub channel to be viewed, where a frequency difference in matching with the segment number 111 is converted into a difference 109 between e.g. a center frequency of sub channel and a center frequency of a channel. The frequency difference 109 is fed to an NCO(numerically- controlled oscillator) 108, which oscillates a frequency in matching with the signal 109. An output of the NCO 108 is respectively fed to frequency shifters 103 and 105. The frequency shifter 103 shifts the frequency of the output of the NCO 108 on the basis of a base band signal 113, and the frequency shifters 105 cause shifts the frequency of an output 114 of a filter to undergo inners shift.

IPC: H04N5/21
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a noise reduction correct by which a noise is reduced without losing a contour component and no unnatural image part is produced. SOLUTION: The noise reduction circuit is provided with a high pass filter 12, a level limit section 22, and a substractor section 20, the level limit section 22 outputs an extracted signal to the substractor section 20 as it is when an absolute value of the signal extracted by the high pass filter 12 is not more than a setting value Sa and limits an amplitude of the extract signal and the limited signal is outputted to the subtractor section 20 when the absolute value is the setting value Sa or over.  That is, when the absolute value of the extracted signal is the setting value Sa or over, it is discriminated to be a contour component, the original video signal is outputted almost as it is, and when the absolute value of the extracted signal is the setting value Sa or below, the extracted signal is discriminated to be a noise component, it is eliminated form the original video signal and the result is used for an output video signal so as to reduce the noise without losing its contour component. In the amplitude limit operation of the level limit section 22, a sudden change in the output signal of the level limit section 22 before and after the setting value Sa is suppressed to prevent appearance of a natural image.
