    摘要： A radio positioning system includes a plurality of base stations, each receiving a radio wave from a mobile terminal, and including a first base station whose position coordinates are known and a second base station whose position coordinates are unknown. The system also includes a distance measuring unit that measures a distance between the first and the second base stations based on the exchanging the radio waves; a position-coordinate calculating unit that calculates position coordinates of the second base station based on the measured distances; a determination control unit that determines a time reference station out of the base stations, and controls the time reference station to transmit a time reference pulse; and a distance-measurement control unit that calculates, using the time difference, a time difference between reception times of the wave signal at the base stations, and calculates position coordinates of the mobile terminal based on the time difference.

    摘要： The communication apparatus employing the non-coherent scheme is used in the UWB-impulse radio system. In order to make it possible to reliably realize long-distance communication, while observing the reference values of the average radiation power and the peak radiation power, and also to realize high-speed short-distance communication, the apparatus includes an impulse adjusting unit which adjusts, according to the distance between two communication apparatuses detected by the distance detecting unit, the amplitude and the repetition frequency of impulses used in radio communication between the two communication apparatuses.
