  • Publication number: 20020094035
    Abstract: A vehicle-vehicle communication system includes an in-vehicle wire LAN established in a vehicle. The in-vehicle wire LAN includes a plurality of devices connected by optical fiber links. A terminal for radio vehicle-vehicle communication is connected to the in-vehicle wire LAN by the optical fiber link. The terminal receives an optical digital signal in a predetermined format from the in-vehicle wire LAN. The terminal includes a light controlled oscillator and applies the received optical signal to the light controlled oscillator. The light controlled oscillator outputs a transmission signal of a frequency shifted from a predetermined frequency according to the intensity of the applied optical signal. Thus the terminal generates the transmission signal using FSK-modulation technique without converting the format of the optical signal into another format. The transmission signal is transmitted to a device in another vehicle via radio waves.

  • Publication number: 20020034950
    Abstract: A Micro-cell is formed to include a plurality of spot-cells. Communication is executed between a micro-cell base station and a mobile terminal in the micro-cell, and between a spot-cell base station and the mobile terminal in the spot cell. The micro-cell base station and spot-cell base stations are connected to an integrated base station. A signal transmitted to the micro-cell base station from the mobile terminal is transferred to the integrated base station and information transmitted to the mobile terminal is transferred to the micro-cell base station and/or spot-cell base station from the integrated base station. The respective integrated base stations are connected to a server via a dedicated backbone to enable a large-capacity transmission.

  • Publication number: 20020002045
    Abstract: A radio communication system between a mobile terminal station of a vehicle and a plurality of roadside fixed base stations is so constructed that communication areas of the base stations do not overlap with each other and satisfy the following two conditions. Condition (i): each communication area is defined so that there cannot be a plurality of terminal stations simultaneously. Condition (ii): it is needless to perform multiple access such as time division in the communication area and capable of affording the whole band and all the communication time allocated to one communication area to one terminal station and broad band communication becomes possible. Thus, each mobile terminal station can utilize all the frequency band allocated for service.

  • Publication number: 20010044315
    Abstract: A radio communication system performs radio communication between a terminal station installed on a vehicle and a plurality of base stations provided along a roadside. The system detects a vehicle traveling speed in each communication area formed by each base station. The vehicle traveling speed is detected by a method which uses radio communication between the terminal station and the base stations. The time of the vehicle stay in the communication area is estimated based on the detected vehicle traveling speed, and the length of a packet is determined based on the estimated time of the vehicle stay in the communication area. In this way, the present system performs data transmission using a packet of an appropriate length according to the detected vehicle traveling speed.

  • Patent number: 5999575
    Abstract: There is disclosed a channel separating filter apparatus for separating a frequency-multiplexed signal comprised of channel signals into respective channel signals. A frequency-converting section frequency-converts the frequency-multiplexed signal into a plurality of channel signals, so that an average value of carrier wave frequencies of two channel signals which are located in the center of the frequency-multiplexed signal and are adjacent to each other becomes substantially zero, and then outputs the plurality of frequency-converted channel signals. Thereafter, a channel separating section separates the plurality of frequency-converted channel signals outputted from the frequency-converting section into respective channel signals each having only a frequency component of each channel signal, thereby separating the frequency-multiplexed signal into at least two channel signals.
