PROBLEM TO BE SOLVED: To provide a short-range radio system capable of securing the establishment of short-range radio communication.SOLUTION: A noise monitoring unit 15 determines that noise is occurring under the communication environment of short-range radio if it detects a voltage change corresponding to noise reception at a communication antenna 11 on a vehicle 1. A noise cancellation unit 16 outputs reverse-phased energy having a waveform with a reverse phase to the noise from the communication antenna 11 on the vehicle 1 when the noise is detected, and cancels the noise occurring under the communication environment.SELECTED DRAWING: Figure 1

    【課題】近距離無線の通信成立性を確保することができる近距離無線システムを提供する。【解決手段】ノイズ監視部15は、車両1の通信アンテナ11でノイズ受信に準じた電圧変化を検出すると、近距離無線の通信環境下にノイズが発生していると判断する。ノイズ消去部16は、ノイズが検出されたとき、車両1の通信アンテナ11から、ノイズに対して逆位相の波形をとる逆位相エネルギーを出力し、通信環境下に発生しているノイズを打ち消す。【選択図】図1
