Abstract:
In this paper, we describe simultaneous localization and communication methods using acoustic signals transmitted simultaneously from multiple speakers. In the case where short-time and narrow-band acoustic signals are used, the interference of signals could cause a systematic error of localization and communication depending on the modulation value. To reduce this systematic error, a noninterference region was constituted in the received signal, and localization and demodulation were processed using this region. Through simulation and real-environment experiments, it was confirmed that the proposed method can reduce the systematic error.
