RADIO TERMINAL DEVICE, RADIO BASE STATION DEVICE, RADIO RANGING SYSTEM, AND RATIO RANGING METHOD |
摘要 |
Disclosed are a radio terminal device and the like, which achieve an improvement in the accuracy of ranging between a UWB reader and a UWB tag regardless of whether an active method or a semi-passive method. In a terminal (300), a timing control unit (340) outputs, to a transmission amplifier (350), a control signal for performing on-off control such that on the basis of the reception timing of a pulse signal transmitted from a base station (200) and a representative value of a circuit delay time required from when a reception pulse signal is received until a transmission pulse signal generated in response to a detection signal of the reception pulse signal is transmitted, the transmission amplifier (350) amplifies a reradiation pulse generated in response to a detection signal of the pulse signal transmitted from the base station (200); and a re-reradiation pulse generated in response to a detection signal of the reradiation pulse. |
