生体を伝送路とした超音波通信の 精度向上に関する研究

抄録

Our research team has proposed the novel communication method for purpose of application to wearable devices. This communication uses the human body as a transmission path and two kinds of energy, electric field and ultrasonic waves are applied hybridly. Therefore, we call this method hybrid communication. To adopt the feature of those energies, this system can realize high usability and secure communication. In this study, I have particularly worked on the improvement of the accuracy on the ultrasonic wave communication. I have improved transmission error rate by changing the modulation method from the amplitude shift keying to the phase shift keying. In addition, I have developed the synchronization method suitable for the ultrasonic wave communication.
