    摘要： Disclosed are a system and a method for transceiving data in an audio frequency band. The system includes a data input unit to input data for acoustic communication into an audio signal, a transmitting unit to transmit the audio signal including the data in the audio frequency band, and a receiving unit that receives the audio signal including the data and performs synchronization of the audio signal through a matched filtering using a matched filter in order to extract the data according to predetermined extraction processing. The data to be transmitted are added to an audio signal and the audio signal is transmitted in the audio frequency band, so that the data for the acoustic communication are effectively transmitted to the recipient in the audio frequency band.

    摘要： 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.
