Abstract

Acoustic data transmission enables a short-range wireless communication between the loudspeaker and microphone. A transmitter embeds a data stream into a base audio signal such as music or commercial advertisement and broadcasts the data through the air by playing back the data-embedded sound using a loudspeaker. A receiver picks up the sound signal using microphone and extracts the hidden message. In our previous work, we proposed an acoustic data transmission system which takes advantage of the phase modification of the modulated complex lapped transform (MCLT) coefficients. In this letter, we propose several techniques to realize a more robust communication system in real noisy environment.
