    摘要: A wireless communication device is provided to carry out correlation peak detection processing properly and efficiently in intermittent receiving unit. If a correlation peak is not detected in a first period in which a correlation peak detecting unit detects the correlation peak at a default frequency and a first frequency in a detecting period of a coarse frequency deviation detecting unit in the first period, a control unit makes the correlation peak detecting unit carry out the peak detection at the first frequency in a second period. If the correlation peak is detected in the correlation peak detecting unit and a second frequency is detected in a detecting period of a fine frequency deviation detecting unit in the first period, the control unit makes the correlation peak detecting unit carry out the peak detection at the first and second frequencies in a third period.

    摘要: A signal processing unit and a wireless communication device are provided for making it possible to detect a frequency by means of a small scale operation circuit in a short time. The signal processing unit and the wireless communication device are comprised of a carrier data generating unit; a carrier demodulation unit; a matched filter unit that divides carrier demodulated data into a plurality of portions, carries out despread processing and accumulating operation processing as partial correlation processing, further carries out full addition processing for the partial correlation processing result, and outputs correlation detected data; a correlation peak detecting unit that detects a correlation peak from the correlation detected data and outputs correlation peak position information; a coarse frequency deviation detecting unit that outputs a frequency deviation amount with respect to the carrier demodulated data to the carrier data generating unit; and a fine frequency deviation detecting unit that outputs a fine frequency deviation amount from the correlation detected data and the correlation peak position information to the carrier data generating unit.

    摘要: An input video signal is applied to a transmission line first through a time direction emphasizer for emphasizing the levels of time direction high frequency components of the video signal, relative to the levels of low frequency components thereof; secondary through a vertical direction emphasizer; and thirdly through a horizontal direction emphasizer. Further, the received video signal is outputted as an output video signal from the transmission line first through a horizontal direction deemphasizer for deemphasizing the levels of horizontal direction high frequency components of the video signal, relative to the levels of low frequency components thereof; secondary through a vertical direction deemphasizer; and thirdly through a time direction deemphasizer. The emphasis and deemphasis method enables the dynamic range of the transmission line to be utilized effectively, while preventing erroneous operation on the reception side.
