Abstract：
Transfer function analysis plays an important role in the investigation of intra-body communication (IBC). In this paper, the voltage distribution based on the quasi-static electric field modeling of human limb for galvanic coupling IBC is analyzed, transfer function of physical channel from 1 Hz to 1MHz is derived and proposed. The attenuation in transfer function shows that lower attenuation is obtained in frequency band from 20 kHz to 1 MHz. Moreover, rectangular pulse is utilized as the input to evaluate this system transfer function. The results in rectangular pulse response indicate separation of distance between transmitter and receiver is the major consideration in designing galvanic coupling IBC system. Finally, this paper reveals bit error rate (BER) under different distances for binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK) and 8PSK modulation schemes. © 2012 IEEE.
