A High-Frequency Pulse Transmission System on Human Body Area: Simulation and Analysis

With the rapid progress of electronic and information technology, an expectation for the realization of body area network (BAN) has risen. In this study, we proposed a pulse transmission system with frequencies at dozens of megahertzes. The system was based on an impulse radio (IR) scheme with bi-phase modulation. By using the frequency-dependent finite difference time domain (FD2TD) method, we investigated the on-body transmission characteristics and derived a path loss expression. We also investigated the influences of Gaussian noises and other narrow-band interferences on the communication link budget and bit error rate (BER) performance.
