SYSTEM AND METHOD FOR REDUCING DATA RECEPTION ERROR IN ACOUSTIC COMMUNICATION IN AUDIBLE FREQUENCY RANGE, AND APPARATUS APPLIED THERETO

Provided is a data reception error reduction system and method in acoustic communication in audible frequency range, and an apparatus applied thereto. The data reception error reduction system in the acoustic communication in audible frequency range may be configured to reduce a data reception error in a receiver by taking into consideration that a sound signal is noisy and is significantly affected by a change in the ambient environment when the acoustic communication is performed in the audio frequency band through modification of an audio signal or adding of a predetermined signal to an audio signal. Accordingly, the data reception error may be reduced in the receiver even in an environment where a sound signal is noisy and is significantly affected by a change in the ambient environment, and reliability of data transmission may increase.
