| 摘要 |
The present invention relates to a sonic wave communication system where a sonic wave receiver receives a sonic wave signal outputted from a sonic wave receiver and analyzes the sonic wave. The sonic wave receiving part extracts a corresponding frequency from a sonic wave signal which the sonic wave receiving part receives. A receiving frequency is recognized by matching the extracted corresponding frequency to a setting frequency table. Receiving data is identified by matching the receiving frequency to a corresponding data table. Thereby, a sonic signal including frequencies can be simultaneously identified. |
