Influence of Gender and Physical Constitution on the ISK-CC-HBC Modulation Scheme

In this paper, the influence of the human body communication (HBC) channel conditions changes on Inductance Shift Keying (ISK-CC-HBC) is analyzed. In particular in ISK-CC-HBC, information is mapped by impedance change at the transmitter side through switching inductance between signal and ground electrode. To achieve maximum Euclidean distance between the constellation points, and consequently a low bit error rate (BER), correct inductance value is crucial. However, the state of the HBC channel varies depending on the person on which the communication takes place. Therefore, in this paper, the performance of the ISK-CC-HBC system was analyzed to determine the optimal inductance and BER for five persons of different ages and genders.
