| Abstract: | Human body communication (HBC) is being recognized as a new communication technology for mobile and wearable devices in a body area network (BAN). This paper presents co‐channel interference experienced by HBC supporting the physical layer in the IEEE 802.15.6 BAN standard. To analyze the co‐channel interference, a co‐channel interference model is introduced, and space‐domain and time‐domain parameters representing an interference environment are generated using the co‐channel interference model. A new signal‐to‐interference ratio (SIR) parameter depending on the peak amplitudes of the data signals causing co‐channel interference is defined; co‐channel interference can be easily analyzed and modelled using the newly defined SIR. The BER degradation model derived using the co‐channel interference model and SIR in this paper can be effectively used to estimate the performance. |
