Transmitter, receiver and method in a communication system with the human body.

Receiver in a communication system with the human body, comprising receiving electrodes (1 to n) comprising a transmission frame including control frames (300) and data frames (400), first and second switches connected to the electrodes receptor (1 to n), a switching control unit (250) first and second switches (211, 212) for connecting the receiving electrodes (1 to n) to the first and second switches in response to each control frame (300 ), a signal processing unit (214) outputting first and second switches, a preamble detection unit (230) for generating preamble correlation values ​​for the first preamble, and a correlation value processing unit (240) controlling the switching control unit (250) for selecting pairs of receiving electrodes (1 to n) concluding on the basis of correlation values ​​Prea mbule.
