摘要： In a case where there are a plurality of spurious disturbing waves, each of which has a strong peak at a particular frequency, in a transmission band, correlation between the disturbing waves becomes nonconstant so that it becomes difficult to remove the correlation between the disturbing waves. An OFDM demodulator of the present invention includes a symbol integration circuit (131) for integrating a guard correlation signal in a symbol number direction, and an offset removal circuit (132) for removing an offset from the guard correlation signal integrated in the symbol number direction. An amplitude component due to the disturbing wave, which amplitude component is included in the guard correlation signal, is cancelled by the integration in the symbol number direction, so that it is possible to successfully remove the offset from the guard correlation signal. Therefore, it is possible to obtain symbol timing more precisely by use of a maximum value detecting circuit (124), and further, calculate a phase rotation amount more precisely by use of a phase finding circuit (125).

摘要： This demodulation device receives and demodulates a digital broadcast wave. This demodulation device includes an RF search control unit (41) and a GI search control unit (42). The RF search control unit (41) determines whether or not there is a broadcast wave in a certain channel, in accordance with an intensity of a signal outputted from a tuner (12) for receiving a digital broadcast wave. The GI search control unit (42) determines whether or not the broadcast wave is digital, based on whether or not the signal outputted from the tuner (12) contains a guard interval. Thus, the demodulation device is capable of efficiently searching for a channel containing a digital broadcast wave.

摘要： A method and apparatus for detecting the traveling position and direction of an unmanned vehicle of an autonomous guidance system, wherein pairs of marks are provided along a course on which the unmanned vehicle is to travel and disposed perpendicularly to the course respectively, and at the unmanned vehicle are provided sensors which can detect the marks and specify the relative positions of the marks with reference to the traverse direction of the vehicle body, thereby obtaining the traveling position and/or direction of the vehicle by the relative positions of each pair of marks and a time difference between the time points when either of the marks and another mark being detected respectively or a travel distance between the time points in time. Hence, the traveling position and direction can be accurately and rapidly detected and a shift of the vehicle from the guide course can be quickly eliminated.

摘要： This invention relates to a novel guiding method for autonomous travelling vehicle in which the number of the rotation of wheels mounted on both the right and left sides are individually detected when guiding the vehicle along the predetermined route by independently controlling the rotation of wheels mounted on both the right and left sides, and then based on the number of the rotations of these wheels and factors, such as the tread, determined by specification of the vehicle, the position and the azimuth of the vehicle are estimated. Then, based on the estimated position and the azimuth of the vehicle by referring to the predetermined route, the target position is set, and then, the vehicle is made to travel toward the set target position. Setting of the target positions and making the vehicle travel toward the set target position are repeated so that the vehicle is guided toward the route being set. When marks are detected while the vehicle travels, the position and azimuth of the vehicle are corrected, and at every time of correcting, the deviations of the position and azimuth are detected. Depending on whether the detected deviation is related to the position or the azimuth, the factor related to the detected deviation is varied and guiding of the vehicle is further executed.
