Title:
ACOUSTIC COMMUNICATION APPARATUS
Document Type and Number:
Japanese Patent JP2015019264
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To further suppress power consumption of an apparatus by reducing the number of carrier waves used for transmission of a communication signal of a prescribed number of bits.SOLUTION: The acoustic communication apparatus includes an extraction section that divides input bit strings into blocks including a prescribed number of bits each of which is at least 1 and at least one of which is at least 2, and a carrier wave output section that outputs carrier waves defined correspondingly to a pattern of the prescribed number of bits, of carrier waves of different frequencies from each other of the number corresponding to the prescribed number of bits, allocated so as to differ from other blocks to each of the blocks.
