Abstract：

Bit　error　rate　(BER),　which　indicates　the　reliability　of　communicate　channel,　is　one　of　the　most　important　values　in　all　kinds　of　communication　system,　including　intra-body　communication　(IBC).　In　order　to　know　more　about　IBC　channel,　this　paper　presents　a　new　method　of　BER　estimation　for　galvanic-type　IBC　using　experimental　eye-diagram　and　jitter　characteristics.　To　lay　the　foundation　for　our　methodology,　the　fundamental　relationships　between　eye-diagram,　jitter　and　BER　are　first　reviewed.　Then　experiments　based　on　human　lower　arm　IBC　are　carried　out　using　quadrature　phase　shift　keying　(QPSK)　modulation　scheme　and　500　KHz　carries　frequency.　In　our　IBC　experiments,　the　symbol　rate　is　from　10　Ksps　to　100　Ksps,　with　two　transmitted　power　settings,　0　dBm　and　-5　dBm.　Finally,　the　BER　results　were　obtained　after　calculation　by　experimental　data　through　the　relationships　among　eye-diagram,　jitter　and　BER.　These　results　are　then　compared　with　theoretical　values　and　they　show　good　agreement,　especially　when　SNR　is　between　6　dB　to　11　dB.　Additionally,　these　results　demonstrate　assuming　the　noise　of　galvanic-type　IBC　channel　as　Additive　White　Gaussian　Noise　(AWGN)　in　previous　study　is　applicable.　©　2013　IEEE.
