“…The improved channel model suggests that the noise caused by the power line can be suppressed with a common-mode choke (CMC). It was experimentally demonstrated that the noise is typically decreased by about 20 dB with the CMC [9], [10] and that the bit-error ratio (BER) of PAN channels is actually reduced with the CMC [11]. Although the CMC is effective for reducing noise due to the power line, it is useless for noise originating from other sources.…”

Many application systems of capacitively coupled personal area networks (CC-PANs) are installed in the vicinity of walls. We therefore investigated noisy-channel models of a CC-PAN in consideration of a wall and a noise-reduction mechanism (NRM). Equivalent circuits representing the proposed channel models can be reduced to a Wheatstone bridge. It is found from the model that the noise is suppressed when the Wheatstone bridge is balanced. In practical CC-PAN systems, such a balanced condition can be realized by tuning a variable capacitor introduced as the NRM. The validity of the noisy-channel models and NRM is experimentally demonstrated.Index Terms-Channel models, electromagnetic coupling, personal area networks, signal to noise ratio.
