  • Patent number: 10759426
    Abstract: A first wireless device is mountable in a vehicle. An acquiring unit acquires position information on the vehicle in which the first wireless device is mounted. A calculating unit calculates a difference between the position information acquired by the acquiring unit and an ideal route for the vehicle. A communication unit transmits a packet signal that contains the difference calculated by the calculating unit and the position information acquired by the acquiring unit.
    Type: Grant

  • Patent number: 6973136
    Abstract: A phase comparator (106) compares a phase of the output signal of the quadrature modulator (104) with the phase of the signal obtained by frequency-converting the output signal of a first VCO (101) via the second VCO (102) and the first mixer (108). A PLL modulator includes a low-pass filter (107) filters a component below a predetermined frequency of the output signal of the phase comparator (106) and supplying the resulting signal to the frequency control terminal of the first VCO (101). The output signal (TS1) of the first VCO (101) is a modulated signal conforming to a modulation system having a constant envelope waveform, while the output signal of the quadrature modulator (104) is input to the first band-pass filter (110) and the output signal (TS2) of the first band-pass filter is a modulated signal conforming to a modulation system accompanied by an amplitude component as information.
