Empirical Channel Model for Human Body Communication

Abstract

In this letter, an empirical channel model for human body communication (HBC) is presented based upon impulse response. For a channel model over a wide range of frequencies between 5 and 80 MHz, the amplitude of an impulse response is modeled with a random variable at each sampling point; the random variable is found using empirically obtained impulse responses with respect to multiple subjects of 70 human subjects. This empirical channel model is obtained when a signal transmitter and receiver are located on opposite hands. However, it provides a practical way to estimate the performance of HBC systems within an environment of multiple users and various devices.
