Abstract：

Transfer　function　of　intra-body　communication　(IBC)　helps　the　understanding　of　signal　transmission　mechanism　and　hints　for　efficient　communication　system　design.　In　this　paper,　transfer　function　with　phase　information　based　on　quasi-static　electromagnetic　(EM)　field　modeling　for　a　galvanic-type　IBC　limb　is　briefly　reviewed.　Then　the　compensation　factor,　which　is　calculated　by　the　minimum　mean　square　error　(MMSE)　method,　is　introduced　to　correct　the　inevitable　deviation　in　actual　shapes　of　human　limb　and　electrical　properties　of　tissues.　To　verify　the　effectiveness　of　correction　factor,　the　square　wave　response　is　calculated　and　experimentally　measured.　Eventually,　our　results　demonstrate　good　agreement　between　theoretical　calculation　and　experimental　measurement.　©　2013　IEEE.
