| 摘要 |
FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication equipment and can be used for data transmission considering contactless state of a human body, at which a central frequency is chosen in different ranges in a communication system by means of a human body. The invention proposes a system of communication by means of a human body, in which central frequency can be easily moved, and namely, the invention proposes a data transmission device containing a frequency shifter that shifts an output signal of a multiplexer to the specified frequency to allow for movement of central frequency. Besides, the second version proposes a system of communication by means of a human body, which controls not only choice of central frequency and minimisation of a transmission band, but data transmission rate and modulation as well, and therefore, it can establish stable communication in contactless state of a human body.EFFECT: technical result consists in maximisation of efficiency of a band and data transmission considering contactless state of a human body.19 cl, 10 dwg |
