Abstract:
This paper proposes a method to process the data representing the sound that is used to determine the indoor position of objects. A scheme is proposed and its theoretical validity is confirmed by numerical simulation using MATLAB. The scheme is to modulate a sound source based on information or data obtained before diffusion (spread spectrum) by an M sequence code. The experimental setup includes a speaker and a microphone, and the bit error rate is evaluated by changing experimental conditions such as the transmitting frequency and the order of the M sequence code. This fact leads to the realization of the system by sound, to provide both indoor positioning and sensor data transmission functions.
