| description | PROBLEM TO BE SOLVED: To improve the communication quality of voice transmitted from a mobile station. SOLUTION: An inductive radio communication system includes a plurality of reception devices which receive high frequency signals transmitted from a mobile station and inductively coupled to an inductive line, a first selection means for inputting the high frequency signals received at the reception devices, comparing reception levels of the high frequency signals, and selecting a predetermined number of high frequency signals from among signals with a good reception state, and a second selection means for inputting voice signals in which the high frequency signals selected by the first selection means demodulated, and selecting a signal in which a ratio between a signal and a noise is best among the voice signals inputted.
