TRANSMITTER, RECEIVER AND METHOD OF THE SAME IN HUMAN BODY COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a receiver in a human body communication system realizing efficient and stable transmission and reception.

SOLUTION: The receiver includes: a reception electrode section 200 receiving a transmission frame including a control frame and a data frame; first and second switches 211 and 212 connected to the reception electrode section 200; a switching control section 250 for performing switching control so that the reception electrode section 200 is selectively connected to the first and second switches 211 and 212 in accordance with the control frame by following a previously set rule whenever the control frame is inputted; a signal processing section 214 which signal-processes the transmission frame outputted from the first and second switches 211 and 212; a preamble detection section 230 for detecting a first preamble from the control frame in the transmission frame and generating a preamble correlation value; and a correlation value processing section 240 for controlling the switching control section 250 to select a final reception electrode pair in the reception electrode section 200 based on the preamble correlation value.
