Title:
SYSTEM AND METHOD FOR SYNCHRONISATION IN AUDIBLE-FREQUENCY-RANGE ACOUSTIC COMMUNICATION TRANSMISSIONS, AND A DEVICE USED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2011/074757
Kind Code:
A1
Abstract:
Disclosed are a system and method for synchronisation in audible-frequency-range acoustic communication transmissions, and a device used therewith. In the system for synchronisation in audible-frequency-range acoustic communication transmissions according to the present invention, while carrying out synchronization in a receiver for acoustic communication when undertaking acoustic communication in the audible frequency range either by modifying an audio signal itself or adding a specific signal to the audio signal, correlations are determined in various sample units, rather than determining correlations for each sample, such that the synchronisation performance is not reduced even if there is a reduction in the calculated amount. Consequently, the present invention can resolve a problem which has been a factor impeding the supply of acoustic communication services in the audible frequency range.
