Title:
高速データ伝送のための人体通信システム
Document Type and Number:
Japanese Patent JP4714787
Kind Code:
B2
Abstract:
Provided is an intra-body communication system which enables high-speed data transmission while limiting the frequency band of a signal being transmitted through a human body to a frequency range (e.g., 30-40 MHz) where the human body can maintain waveguide properties and enables stable intra-body communication by minimizing interference by other users or other electronic devices. A transceiver of the intra-body communication system for high-speed data transmission includes: a source encoder for encoding source information to digital transmission data; a channel error prevention unit for inserting a redundant bit to the encoded transmission data; a mapper for symbolizing the transmission data outputted from the channel error prevention unit; a spreader for performing spread spectrum on the symbolized transmission data in a frequency domain; and a pulse shaping and modulator for generating a baseband signal with a band range limited to a frequency range where the human body retains waveguide properties.
