Patent Searching and Data


Title:
音波通信装置及び方法
Document Type and Number:
Japanese Patent JP6454007
Kind Code:
B2
Abstract:
The present invention relates to a device for sound wave communication, which transmits and receives sound waves so as to exchange data. An embodiment of the present invention may comprise: a hardware correction table for setting a correction frequency band in which a correction frequency is allocated to each correction value for correcting an error according to the hardware characteristic of a sound wave transmission unit, wherein a reference correction frequency is allocated to correction value "0"; the sound wave transmission unit for generating data frequencies at a predetermined base decibel level allocated to data digits, generating separate reception filter frequencies at the base decibel level for receiving data carried by a sound wave transmitted from the nearest location when sound waves are received, and generating the correction reference frequency at the base decibel level for correcting hardware transmission; and a sound wave reception unit for receiving a sound wave signal transmitted from the sound wave transmission unit, extracting decibel levels at each of the data frequencies to form an array of decibel levels, correcting the array by shifting the array by a correction value extracted using the hardware correction table, and reconstructing data by extracting, in descending order of decibel levels, as many data frequencies as the number of array factors allocated to the separate reception filter frequencies having the highest decibel level among a band of separate reception filter frequencies.
