Abstract: front page image
(EN)The present invention proposes a method for transmitting data considering a non-contact state of a human body, while selecting a central frequency in various ranges in the human body communication system. To this end, a first embodiment of the present invention proposes a human body communication system in which a central frequency can be simply moved, and specifically, proposes a data transmission apparatus comprising a frequency shifter which shifts the output of a multiplexer into a specified frequency so as to enable the central frequency to be moved. In addition, a second embodiment of the present invention proposes a human body communication system which controls not only central frequency selection and transmission band minimization, but also a data rate, modulation, etc, and thus can perform stable communication in a non-contact state of a human body. Through this, it is possible to maximize the band efficiency, and to transmit data considering a non-contact state of a human body.
(FR)L'invention concerne un procédé de transmission de données tenant compte d'un état de non contact d'un corps humain, tout en sélectionnant une fréquence centrale sur diverses plages du système de communication de corps humain. Un premier mode de réalisation de l'invention concerne un système de communication de corps humain dans lequel une fréquence centrale peut être déplacée simplement, et plus particulièrement un appareil de transmission de données comprenant un décaleur de fréquence qui décale la sortie d'un multiplexeur jusqu'à une fréquence spécifique, de sorte à permettre le déplacement de la fréquence centrale. Un deuxième mode de réalisation de l'invention concerne un système de communication de corps humain qui commande non seulement la sélection de fréquence centrale et la minimisation de la bande de transmission, mais également le débit de données, la modulation de données, etc., ce qui permet d'établir une communication stable dans un état de non contact de corps humain. La présente invention permet d'augmenter au maximum l'efficacité de bande et de transmettre des données en tenant compte d'un état de non contact de corps humain.
(KO)본 발명은 인체 통신 시스템에서 다양한 범위의 중심주파수를 선택하면서도 인체의 비접촉 상황도 고려하여 데이터를 전송하는 방안을 제안한다. 이를 위해 본 발명의 제1실시예에서는 중심주파수를 간편하게 이동할 수 있는 인체 통신 시스템을 제안하며, 특히 중심주파수의 이동이 가능하도록 다중화기의 출력을 특정 주파수로 천이시키는 주파수 천이기를 포함하는 데이터 전송 장치를 제안한다. 또한 본 발명의 제2실시예에서는 중심 주파수의 선택, 전송 대역의 최소화 뿐만 아니라, 데이터 속도, 변조 등을 제어함으로써 인체의 비접촉 상황에서도 안정적으로 통신할 수 있는 인체 통신 시스템을 제안한다. 이렇게 함으로써 대역 효율을 극대화할 수 있을 뿐만 아니라 인체의 비접촉 상황도 고려한 데이터의 전송이 가능하다.
