DATA RECEIVING ERROR REDUCTION SYSTEM AND METHOD IN AUDIO FREQUENCY BAND SOUND COMMUNICATION, AND DEVICE APPLIED THERETO
Document Type and Number:
WIPO Patent Application WO/2011/078458
Kind Code:
A1
Abstract:
The present invention provides a data receiving error reduction system and method in audio frequency band sound communication, and a device applied thereto. According to the present invention, the data receiving error reduction system in the audio frequency band sound communication includes a feature for reducing a data receiving error in a receiver, by considering that a sound signal has severe noise due to the nature of the audio signal and is influenced a lot by peripheral environmental changes when the audio signal is transformed or sound communication is performed in an audio frequency band by adding a particular signal to the audio signal. Thus, the invention is capable of increasing reliability of data transmission by reducing the data receiving error in the receiver, even in an environment in which the sound signal has severe noise due to the nature of the audio signal and is influenced a lot by peripheral environmental changes when the audio signal is transformed or the sound communication is performed in the audio frequency band by adding the particular signal to the audio signal.
