| Outline of Final Research Achievements |
In this research, a hybrid vibration-based communication method, which combines a multi-step amplitude shift keying and a pulse position modulation, was proposed and evaluated, aiming at realizing the high-speed and stable communication. The evaluation results validated the high-performance vibration-based communication without dependence on specifications of motor for generating vibrations and acceleration sensor for detecting vibrations. More concretely, it was clarified that the data rate of 6.3bps and the communication accuracy of 96.0% with the multi-step amplitude shift keying, and the data date of 3.2 to 5.5 bps and the communication accuracy of 98.7% with the pulse position modulation can be achieved.
